How to Stop the Routine

[BeKirra]

Hi ALL,
The following is a sample of a routine structure:

(defun c:TEST (/ A1 A2 A3)
(MODULE 1)
(MODULE 2)
(MODULE 3)
(MODULE 4)
; the routine would continuously jump to MODULE 6 if MODULE 5 is not executed.
(MODULE 5)
; the routine should stop without MODULE 6 running if MODULE 5 is executed.
(MODULE 6)
); end of defun

I don't see a "IF" statement can simply apply to this routine because each module contains several commands/functions.

Your helps are much appreciated.
Thanks in advance.

Whatever determines if module 5 should run becomes "condition" below...

(if condition
  (module 5)
  (module 6)
)

and if (module 5) is actually a program written out, you would have to inclose it with (progn)

Whatever determines if module 5 should run becomes "condition" below...

(if condition
(module 5)
(module 6)
)

A small but great tip!
Thanks to both of you.
