The <TT
CLASS="application"
>LifeLines</TT
> programming subsystem
lets you produce reports in any style or layout. You may
generate files in <TT
CLASS="application"
>troff</TT
>,
<TT
CLASS="application"
>Postscript</TT
>,
<TT
CLASS="application"
>TeX</TT
>, <SPAN
CLASS="acronym"
>SGML</SPAN
> or any
other <SPAN
CLASS="acronym"
>ASCII</SPAN
>-based format, for further text
processing and printing. You access the report generator by
choosing the r command from the main menu. You may also use
the programming subsystem to create query and other processing
programs that write their results directly upon the
screen. For example, there is a
<TT
CLASS="application"
>LifeLines</TT
> program that computes the
relationship between any two persons in a database.
</P
><P
>
Each <TT
CLASS="application"
>LifeLines</TT
> program is written
in the <TT
CLASS="application"
>LifeLines</TT
> programming
language, and the programs are stored in normal files. When
you direct <TT
CLASS="application"
>LifeLines</TT
> to run a
program, it asks you for the name of the program file, asks
you where you want the program's output written, and then runs
the program.

For example, say you want <TT
CLASS="application"
>LifeLines</TT
>
to generate an ahnentafel (ancestor) report for Tom Wetmore.
Such a report would show Tom Wetmore, his parents, grandparents,
great-grandparents, and so on. It would like like the following:

Say this program is in the file
<TT
CLASS="filename"
>ahnentafel_tutorial</TT
>. When you choose the
<B
CLASS="keycap"
>r</B

<TT
CLASS="application"
>LifeLines</TT
> asks:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="screen"
> What is the name of the report program?
enter string:

</P
><P
>
You enter
<TT
CLASS="userinput"
><B
><TT
CLASS="literal"
>ahnentafel_tutorial</TT
></B
></TT
>. Since the
program generates a report,
<TT
CLASS="application"
>LifeLines</TT
> asks where to write that
report:
<TABLE

BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="screen"
> What is the name of the output file?
enter file name:

You enter a file name, say
<TT
CLASS="userinput"

><TT
CLASS="filename"
>my.ahnen</TT

<TT
CLASS="application"
>LifeLines</TT
> reads the program ahnen,
executes the program, and writes the report output to
<TT

reports any syntax or run-time errors found while trying to
run the program.

A <TT
CLASS="application"
>LifeLines</TT
> program is made up of
<SPAN
CLASS="type"
>procedures</SPAN
> and <SPAN
CLASS="type"
>functions</SPAN
>; every
program must contain at least one <SPAN
CLASS="type"
>procedure</SPAN
> named
<TT
CLASS="literal"
>main</TT
>. The <TT
CLASS="literal"
>main</TT
>
<SPAN
CLASS="type"
>procedure</SPAN
> runs first; it may call other
<SPAN
CLASS="type"
>procedures</SPAN
>, <SPAN
CLASS="type"
>functions</SPAN
> and
<SPAN
CLASS="type"
>built-in functions</SPAN
>. In the ahnentafel example
there is only one <SPAN
CLASS="type"
>procedure</SPAN
>.
</P
><P
> In the example program, there are some comments at the top,
to tell the reader a bit about the program. The comments run
from <TT
CLASS="literal"
>/*</TT
> to <TT
CLASS="literal"
>*/</TT
>, and are
not necessary (but are suggested).
</P
><P
>
A <SPAN
CLASS="type"
>procedure</SPAN
> body is a sequence of
<SPAN
CLASS="type"
>statements</SPAN
>. In the example program, the first five
<SPAN
CLASS="type"
>statements</SPAN
> are:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
> getindi(indi)
list(ilist)
list(alist)
enqueue(ilist, indi)
enqueue(alist, 1)
</PRE
></TD
></TR
></TABLE
>
</P
><P
>
The first <SPAN
CLASS="type"
>statement</SPAN
> calls the
<TT
CLASS="function"
>getindi</TT
> (get individual) <SPAN
CLASS="type"
>built-in
function</SPAN
>, which causes
<TT
CLASS="application"
>LifeLines</TT
> to ask you to identify a
person using the zip browse style of identification:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="screen"
> Identify person for interpreted report
enter name:
</PRE
></TD
></TR
></TABLE
>
</P
><P
>
After you identify a person, he or she is assigned to the
variable <TT
CLASS="varname"
>indi</TT
>. The next two
<SPAN
CLASS="type"
>statements</SPAN
> declare two <SPAN
CLASS="type"
>list
variables</SPAN
>, <TT
CLASS="varname"
>ilist</TT
> and
<TT
CLASS="varname"
>alist</TT
>. <SPAN
CLASS="type"
>Lists</SPAN
> hold sequences of
things; there are operations for placing things on lists,
taking things off, and iterating through the list elements. In
the example, <TT
CLASS="varname"
>ilist</TT
> holds a list of
ancestors, in ahnentafel order, who have not yet been reported
on, and <TT
CLASS="varname"
>alist</TT
> holds their respective
ahnentafel numbers.
</P
><P
>
The next two statements call the <TT
CLASS="function"
>enqueue</TT
>
function, adding the first members to both lists. The person
identified by the <TT
CLASS="function"
>getindi</TT
> function is
made the first member of <TT
CLASS="varname"
>ilist</TT
>, and the
number one, this person's ahnentafel number, is made the first
member of <TT
CLASS="varname"
>alist</TT
>.
</P
><P
>
The rest of the program is:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
> while (indi, dequeue(ilist)) {
set(ahnen, dequeue(alist))
d(ahnen) ". " name(indi) nl()
if (e, birth(indi)) { " b. " long(e) nl() }
if (e, death(indi)) { " d. " long(e) nl() }
if (par, father(indi)) {
enqueue(ilist, par)
enqueue(alist, mul(2,ahnen))
}
if (par, mother(indi)) {
enqueue(ilist, par)
enqueue(alist, add(1,mul(2,ahnen)))
}
}
</PRE
></TD
></TR
></TABLE
>
</P
><P
>
This is a loop that iteratively removes persons and their
ahnentafel numbers from the two lists, and then prints their
names and birth and death information. If the persons have
parents in the database, their parents and their parents'
ahnentafel numbers are then put at the ends of the lists. The
loop iterates until the list is empty.
</P
><P
>
The loop is a <SPAN
CLASS="type"
>while</SPAN
> loop statement. The line:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
> while (indi, dequeue(ilist)) {
</PRE
></TD
></TR
></TABLE
>
removes (via <TT
CLASS="function"
>dequeue</TT
>) a person from <TT
CLASS="varname"
>ilist</TT
>, and assigns the person to variable <TT
CLASS="varname"
>indi</TT
>. As long as there
are persons on <TT
CLASS="varname"
>ilist</TT
>, another iteration of the loop follows.
</P
><P

The statement:<TABLE

BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
>
set(ahnen, dequeue(alist))</PRE
></TD
></TR
></TABLE
>is an <SPAN
CLASS="type"
>assignment</SPAN
> statement. The second argument is evaluated; its value is assigned to the first
argument, which must be a variable. Here the next number in <TT
CLASS="varname"
>alist</TT
> is removed and assigned to variable
<TT
CLASS="varname"
>ahnen</TT
>. This is the ahnentafel number of the person just removed from <TT
CLASS="varname"
>ilist</TT
>.
</P
><P
>
The line:<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
>
d(ahnen) ". " name(indi) nl()</PRE
></TD
></TR
></TABLE
>contains four <SPAN
CLASS="type"
>expression</SPAN
> statements; when expressions are used as statements, their values, if any, are
treated as strings and written directly to the report output file. The <TT
CLASS="function"
>d</TT
> function converts its integer
argument to a numeric string. The ". " is a literal (constant) string value. The <TT
CLASS="function"
>name</TT
> function returns the
default form of a person's name. The <TT
CLASS="function"
>nl</TT
> function returns a string containing the newline character.
</P
><P

The next two lines:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
> if (e, birth(indi)) { " b. " long(e) nl() }
if (e, death(indi)) { " d. " long(e) nl() }
</PRE
></TD
></TR
></TABLE
>
write out basic birth and death information about a person. These
lines are <SPAN
CLASS="type"
>if</SPAN
> statements. The second argument in the
conditional is evaluated and assigned to the first argument, which
must be a variable. The first <SPAN
CLASS="type"
>if</SPAN
> statement calls the
birth function, returning the first birth event in a person's
record. If the event exists it is assigned to variable
<TT
CLASS="varname"
>e</TT
>, and the <SPAN
CLASS="type"
>body</SPAN
> (the items between the
curly brackets) of the <SPAN
CLASS="type"
>if</SPAN
> statement is executed. The
<SPAN
CLASS="type"
>body</SPAN
> consists of three <SPAN
CLASS="type"
>expression</SPAN
>
statements: a literal, and calls to the <TT
CLASS="function"
>long</TT
> and
<TT
CLASS="function"
>nl</TT
> functions. <TT
CLASS="function"
>Long</TT
> takes an
<TT
CLASS="parameter"
><I
>event</I
></TT
> and returns the values of
the first <TT
CLASS="structfield"
><I
>DATE</I
></TT
> and
<TT
CLASS="structfield"
><I
>PLAC</I
></TT
> lines in the <SPAN
CLASS="type"
>event</SPAN
>.
</P
><P
>
Finally in the program is:<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="programlisting"
>
if (par, father(indi)) {
enqueue(ilist,par)
enqueue(alist,mul(2,ahnen))

if (par,mother(indi)) {
enqueue(ilist,par)
enqueue(alist,add(1,mul(2,ahnen)))
}</PRE
></TD
></TR
></TABLE
>
</P
><P
>
These lines add the father and mother of the current person, if either or both are in the database, to
<TT
CLASS="varname"
>ilist</TT
>. They also compute and add the parents' ahnentafel numbers to <TT
CLASS="varname"
>alist</TT
>. A father's ahnentafel
number is twice that of his child. A mother's ahnentafel number is twice that of her child plus one.
These values are computed with the <TT
CLASS="function"
>mul</TT
> and <TT
CLASS="function"
>add</TT
> functions.

>Statements</H2
><P
>
There are a number of <SPAN
CLASS="type"
>statement</SPAN
> types. The
simplest is an <SPAN
CLASS="type"
>expression</SPAN
> statement, an
expression that is not part of any other
<SPAN
CLASS="type"
>statement</SPAN
> or
<SPAN
CLASS="type"
>expression</SPAN
>. <SPAN
CLASS="type"
>Expressions</SPAN
> are defined
more fully below. An <SPAN
CLASS="type"
>expression</SPAN
> statement is
evaluated, and if its value is
<SPAN
CLASS="returnvalue"
>non-null</SPAN
> (non-zero), it is assumed
to be a <SPAN
CLASS="type"
>string</SPAN
>, and written to the program output
file. If its value is <SPAN
CLASS="returnvalue"
>null</SPAN
>, nothing
is written to the output file. For example, the expression
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="synopsis"
>name(indi)</PRE
></TD
></TR
></TABLE
>, where <SPAN
CLASS="symbol"
>indi</SPAN
>
is a person, returns the person's name and writes it to the
output file. On the other hand, the expression
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="synopsis"
>set(n, nspouses(indi))</PRE
></TD
></TR
></TABLE
> assigns the
variable <TT
CLASS="varname"
>n</TT
> the number of spouses that
person <TT
CLASS="varname"
>indi</TT
> has, but since
<TT
CLASS="function"
>set</TT
> returns
<SPAN
CLASS="returnvalue"
>null</SPAN
>, nothing is written to the
output file.
</P
><P
>
The programming language includes <SPAN
CLASS="type"
>if</SPAN
> statements,
<SPAN
CLASS="type"
>while</SPAN
> statements and <SPAN
CLASS="type"
>procedure call</SPAN
>
statements, with the following formats:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="synopsis"
>if ([varb,] expr) { statements }
[ elsif ([varb], expr) { statements } ]*

</P

Square brackets indicate optional parts of the statement syntax. An <SPAN
CLASS="type"
>if</SPAN
> statement is executed by first
evaluating the conditional expression in the <SPAN
CLASS="type"
>if</SPAN
> clause. If <SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, the statements in the <SPAN
CLASS="type"
>if</SPAN
> clause are
evaluated, and the rest of the <SPAN
CLASS="type"
>if</SPAN
> statement, if any, is ignored. If the value is <SPAN
CLASS="returnvalue"
>zero</SPAN
>, and there is an <SPAN
CLASS="type"
>elsif</SPAN
>
clause following, the conditional in the <SPAN
CLASS="type"
>elsif</SPAN
> clause is evaluated, and if <SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, the statements in
that clause are executed. <SPAN
CLASS="type"
>Conditionals</SPAN
> are evaluated until one of them is <SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, or until there are no
more. If no conditional is <SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, and if the <SPAN
CLASS="type"
>if</SPAN
> statement ends with an <SPAN
CLASS="type"
>else</SPAN
> clause, the statements in
the <SPAN
CLASS="type"
>else</SPAN
> clause are executed. There are two forms of <SPAN
CLASS="type"
>conditional</SPAN
> expressions. If the <SPAN
CLASS="type"
>conditional</SPAN
> is a
single <SPAN
CLASS="type"
>expression</SPAN
>, it is simply evaluated. If the <SPAN
CLASS="type"
>conditional</SPAN
> is a <SPAN
CLASS="type"
>variable</SPAN
> followed by an <SPAN
CLASS="type"
>expression</SPAN
>, the
<SPAN
CLASS="type"
>expression</SPAN
> is evaluated and its value is assigned to the variable.
</P
><P
>
Note that <SPAN
CLASS="type"
>if</SPAN
> treats null strings as false, but empty strings as true. This has the benefit that
<TABLE

will return <SPAN
CLASS="returnvalue"
>true</SPAN
> if there is a BIRT record, even if it is empty, but will return false if there is no BIRT record
at all.
</P
><P
>
The <SPAN
CLASS="type"
>while</SPAN
> statement provides a looping mechanism. The <SPAN
CLASS="type"
>conditional</SPAN
> is evaluated, and if <SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, the
<SPAN
CLASS="type"
>body</SPAN
> of the loop is executed. After each iteration the <SPAN
CLASS="type"
>expression</SPAN
> is reevaluated; as long as it remains
<SPAN
CLASS="returnvalue"
>non-zero</SPAN
>, the loop is repeated.
</P
><P
>
The <SPAN
CLASS="type"
>call</SPAN
> statement provides procedure calls. <SPAN
CLASS="symbol"
>Name</SPAN
> must match one of the <SPAN
CLASS="type"
>procedures</SPAN
> defined in the
report program. <SPAN
CLASS="symbol"
>Args</SPAN
> is a list of <SPAN
CLASS="type"
>argument</SPAN
> expressions separated by commas. <SPAN
CLASS="type"
>Recursion</SPAN
> is allowed.
When a <SPAN
CLASS="type"
>call</SPAN
> is executed, the values of its <SPAN
CLASS="type"
>arguments</SPAN
> are evaluated and used to initialize the
procedure's <SPAN
CLASS="type"
>parameters</SPAN
>. The <SPAN
CLASS="type"
>procedure</SPAN
> is then executed. When the <SPAN
CLASS="type"
>procedure</SPAN
> completes, execution
resumes with the first item after the call.

The following report language statements are commonly encountered only near the top of a report:

</P
><P

The <SPAN
CLASS="type"
>char_encoding</SPAN
> statement specifies what character encoding scheme is used by the report, so that the
report processor can correctly interpret bytes not in ASCII (e.g., accented letters). An example specifying a character
encoding common in Western Europe:

</PRE
></TD
></TR
></TABLE
>
The <SPAN
CLASS="type"
>option</SPAN
> statement allows the report writer to specify options. The only option currently available is
"explicitvars", which causes any use of variables not previously declared or set to be reported as a parsing error. The
<SPAN
CLASS="type"
>require</SPAN
> statement allows the report writer to specify that this report needs a version of the report
interpreter no older than that specified.
The <SPAN
CLASS="type"
>include</SPAN
> statement includes the contents of another file into the current file; its <TT
CLASS="parameter"
><I
>string</I
></TT
> expression is
the name of another <TT
CLASS="application"
>LifeLines</TT
> program file. It is described in more detail below. The <SPAN
CLASS="type"
>global</SPAN
> statement
must be used outside the scope of any <SPAN
CLASS="type"
>procedure</SPAN
> or <SPAN
CLASS="type"
>function</SPAN
>; it declares a <TT
CLASS="parameter"
><I
>variable</I
></TT
> to have global scope. The
<TT
CLASS="parameter"
><I
>variable</I
></TT
> is initialized to 0.
</P
><P

The report language also includes the following statements, which mimic some common programming languages:

</P
><P

The <SPAN

CLASS="parameter"
><I
>expression</I
></TT
> is evaluated, and its value is assigned
to the <TT

><I
>variable</I
></TT
>. The <SPAN
CLASS="type"
>continue</SPAN

loop. The <SPAN
CLASS="type"
>break</SPAN

CLASS="type"
>return</SPAN
> statement returns from
the current <SPAN
CLASS="type"
>procedure</SPAN

CLASS="type"
>function</SPAN
>. <SPAN
CLASS="type"
>Procedures</SPAN

have return statements with expressions. None of these statements return a value, so none has a direct
effect on program output.

There are four types of expressions: <SPAN
CLASS="type"

CLASS="type"
>variables</SPAN
> and built-in or user defined function
<SPAN
CLASS="type"

>.
</P
><P
>
A <SPAN
CLASS="type"
>literal</SPAN
> is any string enclosed in double quotes; its value is
itself. A <SPAN
CLASS="type"
>number</SPAN
> is any integer or floating point constant;
its value is itself. A <SPAN
CLASS="type"
>variable</SPAN
> is a named location that can be assigned different values during program
execution. The value of a <SPAN
CLASS="type"
>variable</SPAN
> is the last value assigned to it. <SPAN
CLASS="type"
>Variables</SPAN
> do not have fixed type; at
different times in a program, the same <SPAN
CLASS="type"
>variable</SPAN
> may be assigned data of completely different types. An
identifier followed by comma-separated list of expressions enclosed in parentheses, is either a <SPAN
CLASS="type"
>call</SPAN

built-in function or a <SPAN

statement is encountered, the program that it refers to is read at that point, exactly as if the contents of
included file had been in the body of the original file at that point. This allows you to create <TT
CLASS="application"
>LifeLines</TT
>
program library files that can be used by many programs. Included files may in turn contain <SPAN
CLASS="type"
>include</SPAN
>
statements, and so on to any depth. <TT

>LifeLines</TT
> will use the <TT
CLASS="envar"
>LLPROGRAMS</TT

statement is only read once. If multiple include statements are encountered
that include the same file, only the first statement has any effect.

Reference types (denoted above in parentheses) obey "pointer semantics", which is to say that assigning one to another
variable results in both variables pointing at the same data (no copy is made). Therefore, if you pass a string to a
function which changes the string, the caller does not see the change, because a string is not a reference type. On the
other hand, if you pass a table to a function which alters the table, the caller does see the change, because a table is
a reference type.

>Iterators</H2
><P
>
The report generator provides a number of iterator statements
for looping through genealogical and other types of data.
For example, the <SPAN
CLASS="type"
>children</SPAN
> statement
iterates through the children of a family,
the <SPAN
CLASS="type"
>spouses</SPAN
> statement iterates through the spouses of a
person, and the <SPAN
CLASS="type"
>families</SPAN
> statement iterates through the families that a person is a spouse or parent in.
</P
><P
> Usually the first argument to the iterator is an expression that evaluates to an
individual or a family.
The other arguments of the iterator are variable names that are set with values for each iteration.
The last argument is often a variable name used as a counter.
It starts with the value of one and is
increased by one for each iteration of the loop.
After completion of the iteration, these variables have the value null.

For example, the first argument to
<SPAN

>children</SPAN
> is the family that the iterator will operate on.
This iterator will execute the block of commands for each child in the
specified family. The second argument is set to each child in the family
in the order they are listed in the family and the third argument is the
loop counter which starts at one and is incremented by one each time the
the block of commands is executed. The two variables indi and cnt will
have the value null after the iteration has completed.

</P

</P

parameter to both is a list; the second parameter to both is an integer index into the array; and the third parameter to

indexed starting at one. Unassigned elements are assumed to be <SPAN

>
(<SPAN

rsort sorts in order reverse of sort.
The order that sort produces places the smallest element at position 1, and the
largest element at the end of the list, such that <TT

<TT
CLASS="function"

the date format selected with <TT
CLASS="function"
>dateformat</TT
>. The string
supplied specifies the placement of the day, month and year in the string with
%d, %m and %y. A null argument disables the overrided format.
The argument to <TT
CLASS="function"
>stddate</TT
> is normally an event and the
date is extracted from the event and formatted. If the argument is a
date string it is converted using the current date formats.
</P

> The next three functions provide for more complex formatting of dates. Taking
into account the abt, est, cal, bef, aft, fr and to qualifiers on GEDCOM dates.
<TT
CLASS="function"
>complexformat</TT
> selects the format to use. The format
effects only the complex picture, not the format of the date itself.
The function
<TT
CLASS="function"
>complexpic</TT
> can be used to specify a custom picture string
for any or all of the 9 custom format strings. The custom string can be
canceled by passing a null for the string. When a custom picture string is
provided it overrides both the abbreviated and full word picture strings.
<TT
CLASS="function"
>complexdate</TT

formats the date similarly to <TT
CLASS="function"
>stddate</TT

addition of the complex date format string selected.

> These functions provide string handling. Prior to version 3.0.6, many of them used an approach to memory management
chosen for absolute minimal memory footprint. A function using this approach constructed its output string in its own string
buffer, reusing that buffer each time it was called. When a function using this approach returned a string
value it returned its buffer. In consequence the strings returned by these functions were to be either used or
saved before the function was called again.
