It will stay in the first loop forever!

You're right, it will get "locked" up in the first loop and after the pins
have been set the first time, you won't see any changes.

Are you trying pulse the outputs? If so, you can use the PULSOUT command.
Something like this:

Setup:
LOW 1
HIGH 2
LOW 3

Loop:
PULSOUT 1, 5
PULSOUT 2, 5
PULSOUT 3, 5
GOTO Loop

The PULSOUT command will pulse the given pin to the opposite of its initial
state. The second parameter of the command is time, expressed in 2
microsecond units (for a BS2).

If you want the running constantly, you may not be able to do it with the
BASIC Stamp (or any clone, for that matter). My best advice would be to put
that code in the "top" of your program, then divide the rest of the program
into discrete tasks. You can then run the pulsing block in between every
task.

Here's the general idea. You'll need to read a bit of the BASIC Stamp
documentation to fully utilize this:

Setup:
LOW 1
HIGH 2
LOW 3

Main:
PULSOUT 1, 5
PUSLOUT 2, 5
PUSLOUT 3, 5

BRANCH task, [noparse][[/noparse]Task0, Task1, Task2]

Task0:
' do something
task = 1
GOTO Main

Task1:
' do something
task = 2
GOTO Main

Task2:
' do something
task = 0
GOTO Main

I am new to stamps and i was had a quick question.
Is the Stamp capable of doing programs like this:?

Loop1:
High 1
Low 2
High 3
Goto Loop1

Loop 2:
Low 1
High 2
Low 3
Goto Loop2

Or will it get locked up in the first one and just do that one forever or can
the stamp do both at the same time?

Thanks, i was just giving an example with the High and Low Pins, but your
pulsout example brings me another question:
How would you continue with the rest of your program with that loop in there?
