RE: Re[2]: RPG Cycle(exsr as goto)

[Colin Williams <Williamsc@xxxxxxxxxxxxxxxxx>]

I've always found these sorts of discussion useful, if only so that
everyone gets to see the argument from both sides.

     Why are we still on this thread? This has devolved into one of the 
     most ridiculous ever. Could we perhaps move on?

All right, it's two GOTOS that follow a specific set of rules.  A GOTO
tells
the program to branch to a specific location in the code.  An EXSR tells
the
program to branch to a specific location in the code.  The difference
is, as
Brad points out, that it also remembers where it started and branches
back.


I think you can simulate subroutines using GOTO and TAG, although it
could
get very messy if the subroutine is called from a lot of places.

        "BTW, EXSR is a goto.  I use that one, though "   

        [And Brad Said:]  Wrong.  EXSR is a GOSUB (in BASIC speak that
is.)
EXSR jumps to a spot in a program and returns to it's origniating point.
GOTOs do nothing of the sort.
