:::::: The following example shows all the flavors (and a surprise when I invoke the program as rexx ret 1 (on Windows using ooRexx)! The control structure seems to get broken)
<lang rexx>Call sub 1
s=sub(2)
Say 's='s
sub: parse Arg a
Select
When a=1 Then Say 'we''ll return to line 2'
When a=2 Then Say 'we''ll return to the expression in line 2'
Otherwise Say 'we''ll exit the program'
End
Return a</lang>
Output:
<pre>we'll return to line 2
we'll return to the expression in line 2
s=2
we'll exit the program</pre>
== REXX Exit ==
