TEXT
Description
The HEADER_TEXT() function
is the basic print mechanism for PG problems. It concatenates its
arguments and places them in the output text string for inclusion in
the body of an HTML document. It can be used more than once in a PG
source file.
Syntax
TEXT($string1, $string2...);
Params
A list of strings.
Action
Places its concatenated input in $STRINGforOUTPUT
Returns
Nothing
Examples
A barebones PG problem using TEXT:
DOCUMENT();
loadMacros(PGbasicmacros.pl,
PGanswermacros.pl );
TEXT(beginproblem());
TEXT( "Hello", ans_rule() , ".");
ANS(str_cmp("World") );
ENDDOCUMENT();
Notes
TEXT() is mainly used in constructing more abstract
macros, however it can also be useful for directly including strings
into the body of the HTML without any processing. For example, TEXT(beginproblem());
is often placed near the top of a PG problem source file in order to
include "beginproblem"()'s output text, which indicates the number of
the problem and the number of points it is worth.
