I should have explained things a bit more clearly here. I have a PerlHash in forth.pir that contains a Sub for each supported operation. I store this as a global. I then build up a string of PIR that locates subroutines from the global PerlHash and invokes them. I compile this string and execute it. Every time I invoke one of the subroutines from the PIR string I've compiled, I get a new copy of the user stack, which means that I am unable to alter it with any of my subroutines. This seems like a bad thing to me as I try to implement this. But maybe I just don't understand how implement this correctly? -- matt
