Confused on an IF...THEN decimal # check

[Archangel]

Hello all,

I've got my serial comms working great, thanks to all of you! As I'm running my code through the sim, I'm trying to validate the incoming decimal address, with no success. It goes something like this:

hserin [wait("A"),DEC3 boardadd]
            hserout ["Board received A",DEC3 boardadd,13,10]
            IF (boardadd = 000) OR (boardadd > 254) THEN     'THIS IS NOT WORKING!!!!!
                hserout ["Error: Address ",DEC3 boardadd," not valid! Please use 001 to 254.",13,10]
            else        
                write 0,boardadd
                high Progled
                    pauseus 50
                low progled
                read 0,boardaddep
                hserout ["Board address set to ",DEC boardaddep,13,10]
            endif

The "=000" works, but the ">254" doesn't. The code allows me to enter >254. Am I missing something here, or am I trying to compare 2 different formats? I've tried the following with no success:

IF (DEC3 boardadd = 000) or (DEC3 boardadd > 254) THEN...

Hope one of you can help. Thanks a million!

I have a thought . . . Right, wrong or otherwise . . .
your code . .

IF (boardadd = 000) OR (boardadd > 254) THEN

have you tried . . . ?

IF (boardadd <1) OR (boardadd > 254) THEN
