Subject: Re: Keeping variables across requires?

Ah, thanks. With Ruby I'm used to not having to do global/local things; 
I didn't know you could create global ones with $. But now I have 
another problem: The functions I created with lambda {} are now 
returning -1 as their arity.

My new code:

befunge.rb
---
  elsif $instructions.include? operator
    arguments = []
    $instructions[operator].arity.times {arguments.push stack.pop}
    $instructions[operator].call( *arguments )
  else
---

befunge-93.rb (just a sample)
---
  $instructions = {}
  $instructions["!"] = lambda { |a| stack.push !a}
  $instructions["`"] = lambda { |a, b| stack.push b>a ? 1 : 0 }
  $instructions[">"] = lambda { xvel = 1; yvel = 0 }
