Basic Programming newbie

·Just getting started and I need some help with the LOOP statement. How doyou break out of the loop once your input is met?

ie:
DO
IF· (IN3=1) then ???? how do I go tp my next statment once this is me?

LOOP

Next statement Here

Martin Hebel

DO
Loop until (IN3 =1)

You should also be able to do this...

DO
 
  IF IN3 = 1 THEN EXIT
 
LOOP
 
...

Martin,



Thank you very much.

peteraltman:

Note that Chris Savage is using the work "Exit" as a lable·for another part of the program as in...

Main:
DO
· IF IN3 = 1 THEN Go_to_this_part
LOOP

Go_to_this_part:
' do something different here
...

Steve,
I believe EXIT was added with version 2.5 as a means to exit loops cleanly, so it's actually an instruction and not a label.

Correct Martin...I guess I should've stated that...It allows premature exit from DO...LOOP and FOR...NEXT however I believe it to work in this context (conditional outside the function) as well.

Chris, Martin, Steve, and peteraltman--

I am an "old-head" code cutter. The last time I used a language that forced one to utilize a "premature exit" was the 8008 instruction set, one bit at a time! However, I admit that Parallax's implementation of it makes a lot of sense.

Ha! I am LOOKING at the machine I used it on! Wonder what it is worth today? (Nothing, probably.)
