Language::Befunge::lib::PERL - extension to embed Perl within Befunge
The PERL fingerprint (0x5045524c) is designed to provide a basic, no-frills interface to the Perl language.
After successfully loading PERL, the instructions E, I, and S take on new semantics.
Create a new PERL instance.
Shelledpushes a 0 on the stack, meaning that the Perl language is already loaded (e.g. the interpreter is written in Perl).
- 0gnirts = E( 0gnirts )
Evalpops a 0gnirts string and performs a Perl
eval()on it. The result of the call is pushed as a 0gnirts string back onto the stack.
- val = I( 0gnirts )
Int Evalacts the same as
E, except that the result of the call is converted to an integer and pushed as a single cell onto the stack.
