Nono, setjmp/longjmp correspond to catch/throw in Lisp. This is something completely different, it jumps *up* the call history to an enclosing environment. There is only a single entry point to a function in C (and also in Lisp). I don't know PowerBasic, but traditional Basic allowed that, you could GOTO any point in a program, also in other subroutines, just like a JMP in assembly. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
