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 $STRINGforOUTPUTReturns
Nothing
Examples
A barebones PG problem usingTEXT:
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.
