PG basics
-
Basic Perl Syntax
- Fortunately you only need a little knowledge of Perl in order modify or write problems for WeBWorK. If you know more, you can write very powerful macros. It's possible to outgrow many problem generating languages as you become more ambitious about the kind of math problems you'd like to present. This is unlikely to happen with PG because it is based on Perl, and allows you nearly full access to the constructs of that very powerful language.
- The problem text
- Details how The problem text is evaluated and printed when placed within the BEGIN_TEXT .... END_TEXT construction.
