The Devil is in the details. Contrast Rexx with PL/I. In PL/I a SIGNAL
invokes an ON-unit as a subroutine. The On=unit can return to the code
following the SIGNAL, can SIGNAL another condition, or can include a
GOTO, which will pop the stack as appropriate. Note that in PL/I you
cannot do a GOTO into a DO loop from outside.
>I mean, of what use would that be?
Quite a bit if you do it the way PL/I does.
