Hi,
One more thing: if you want to view all of the environment variables and their values use the macro PGinfo.pl and its method listVariables(). Here's an example.
DOCUMENT();
loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"PGinfo.pl",
);
TEXT(beginproblem());
Context()->texStrings;
BEGIN_TEXT
\{ listVariables() \}
END_TEXT
Context()->normalStrings;
ENDDOCUMENT();
