Do...loop question?

I just got the Basic Stamp 2p40 with the demo board and am just
starting to learn it...whenever i enter

'{$STAMP BS2p}

DO

HIGH 5
PAUSE 500
LOW 5
PAUSE 500

LOOP

The LED will run through the cycle once, turning on and then turning
off, but will not loop or repeat like it should. I can get the
desired effect by running

MAIN:
HIGH 5
PAUSE 500
LOW 5
PAUSE 500
GOTO MAIN

This works fine, so I am wondering why the DO...LOOP command is not
working. any ideas...it appears as if the led is twitching like it
wants to start over but isn't.

    Did you call up the PBasic 2.5 directive?

    Hi Mark,

    Your Stamp does not know you want to run PBASIC 2.5

    Just ad the line

    '{$PBASIC 2.5}

    to your code after '{$STAMP BS2p} and your problem will (hopefully)
    disapear.

    Regards,

    Klaus

    You also need this directive...

    ' {$PBASIC 2.5}

    I'm having the same problem including the "Twitching."

    I do have the the ' ($PBASIC 2.5) comment inserted but the "DO LOOP"
    command is not listed.

    I am using the BOE and a BS2 rather than a BS2p.

    I believe the problem may be that the editor I am using is version
    2.1 rather than 2.5. How do I download the 2.5 version?

    Thanks

    The editor version is 2.1 -- the language syntax is called 2.5. If you
    are using the 2.1 editor you can use DO-LOOP in your programs. The
    problem you're having may be related to your serial port -- we've seen
    this before. If you insert a DEBUG line in your program, I'll be the
    problem goes away (I won't explain here, you can search the list as it
    has been covered many times).

    Put this before your DO-LOOP section

    DEBUG "DO-LOOP Demonstration"
