I'll jump in with a "good, legitimate" REMOVE usage.
Most of what we hear about is something like:
IF (LONG.DELIMITED.STRING[1,1] NE "") THEN
LOOP
REMOVE ELEMENT FROM LONG.DELIMITED.STRING SETTING MORE.DATA
* Take Element-specific action
WHILE MORE.DATA DO REPEAT
END
However, I've had a couple of situations where I was parsing a string with
multiple levels of delimiter where nested loops would have been ugly. This
is cleaner and clearer:
IF (ODDLY.DELIMITED.STRING[1,1] NE "") THEN
LOOP
REMOVE ELEMENT FROM ODDLY.DELIMITED.STRING SETTING DELIM
* Take Delimiter-specific action
BEGIN CASE
CASE (DELIM EQ 2) ;* AM-Specific Code
CASE (DELIM EQ 3) ;* VM-Specific Code
END CASE
WHILE DELIM DO REPEAT
END
That being said, I'm glad we have REMOVE available for both uses.
Thanks, Ross.

I have yet to hear of a good, legitimate, use for REMOVE.
Even after 30 or so posts on this topic ;)
