MASM error 202 argument out of range

[retepsnikrep]

I'm working with pbpro 3.01 and a pretty big program ~ 7000 words using the 16F886 and I get the below error x 2.

"error 202 argument out of range, Least significant bits used."

Do I need to worry? The program compilies correctly :?

If I were you I would look at the .lst file for the compiled program and find the instance "argument out of range". This will tell you what variable is the incorrect size you are trying to pass. Yes it could make for some unintended operation....

Trying to pass. Yes it could make for some unintended operation....

Trying to pass?

I don't have any assembler routines in my basic code.

The error seems to relate to this code.

 HChkSum = $E4 + $06 + $02 + ImaMem + RL        'Calculate Read Chksum
HChkSum = $100 - HChkSum                    'Calculate two's complement

HChkSum is a byte variable and I assume must be overflowing as the additions take place or when we try to subtract 100H from it.

Try using decimal 255 in your formula instead of $100. The hex number $100 is equal to decimal 0001 0000 000. This might be a problem with your byte variable.

I meant $100 equal to decimal 0001 0000 0000. Missed a zero.
