I thought he was asking for a way to do something in DCL (and
later in Dave's comment) or a Unix Shell.  A trivial and quite
common task in Unix.  No goto required.  A switch statement or
a bunch of If/then/else statements.  My choice of shells is
still C-shell, but I don't think I have ever used goto. It's
probably the only thing me and Dykstra ever agreed on.

John, if this is what was desired,  I can throw together a
simple C program with return values and a shell script that
will react to that return value.  Would only take a few
minutes.
