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.

        [And Brad Said:]  -snip- 
        "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.
