BILL HEMENWAY wrote something original about GOTO


BH> Is there something like labels and goto in rexx?

REXX does have labels, and has something like 'GOTO'.  It also has
'IF-THEN-ELSE', 'DO WHILE', 'DO UNTIL', 'DO var=start TO end BY step'
and a few other useful constructs.

Okay, so if you want to use a 'goto' (I'll admit they are occasionally
the easiest way to do things), try the following code illustrating the
goto-like 'signal' instruction:

/* REXX example 'not quite a goto' */

do i=1 to 10
  say 'i=' i
  signal out_of_loop /* this is like a goto */
into_loop:    /* this is a label */
 end
exit

out_of_loop:    /* this is another label */
  say 'jumped out of the loop'
  signal into_loop /* this isn't going to work */
