Confused on an IF...THEN decimal # check

[kevlar129bp]

Thanks for your input Joe. If I remember correctly, I tried so many different ways, but to no avail. Although, Dave's solution worked flawlessly so far! Hey guys, without me starting a new thread, I've got 1 more question. This "Master Board" PIC is actually going to be sending serial out to "Daughter" boards with their own PICs. A quick snippet of my code goes like so:

...
case 2
serout portB.1,n9600,[UpdPinLvl] 'CAT5 JACK 1, PIN 2
GOTO Start
...

Is this (basically) the correct syntax if the signal does not route through a MAX232? BTW: UpdPinLvl is a 8 bit integer. OK, so 2 questions: Correctness of syntax aside, what is roughly the max distance between Master and Daughter I could expect with driving it TTL?

Any thoughts would be great!

It's a byte. That's not ok for 1-256?

No it's not. A byte is OK for 0-255.

A byte has 256 states... ZERO is one of them.

It the variable is a number you may want to consider this from the manual

A numeric value preceded by a pound sign ( # ) will send the
ASCII representation of its decimal value. For example, if W0 =
123, then #W0 (or #123) will send “1", “2", ”3".

Distance... Depending on the cable, connections, and the amount of noise in the environment, 30 to 50 feet is about the max distance you can expect. Could get a little more, maybe less.

Thanks guys,
I think I'll just mess with the daughter board when I have more time...the master board was my main focus, and it's good so far. As for the cabling, I'm an Audio-Video-Security installer, so cat5 is a natural fit for me. This is what I've got so far...so we'll just have to road-test the max limits.
