Language::Befunge::IP::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.
Shelled pushes a 0 on the stack,
meaning that the Perl language is already loaded (e.g.
the interpreter is written in Perl).
Eval pops 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.
Int Eval acts the same as
except that the result of the call is converted to an integer and pushed as a single cell onto the stack.
