Funny problem...

Hi all,
I have been doing some fairly simple test routines for my low frequency sampling
project (as per past emails) and am working on a pause 125 to give me 8 samples
per second and simply read the input pin state. and then use some kind of fuzzy
logic to work out whats going on.
BUT... none of my code seems to run (not necessarily work but simple run) unless
I put a debug statement at the start. Just a simple DEBUG CLS and the stamp
jumps in life, but without it the code never runs!! I'm concerned I've fired the
stamp somehow becuase I realised after the fact that the signal I was reading
was 12V and not 5V!! But it seems to be a very strange thing to be broken. With
this debug statement the code runs fine and my output to the LCD works without
it nothing is displayed!!
Anyone any ideas...
Cheers 4 now

believe it or not -- with your serial port. I'll bet you're running on
a laptop, aren't you? If you change the FIFO settings on your port to
minimum values the problem should go away. I saw this firsthand while
conducting a BASIC Stamp programming class in Holland last year.
