Hello,

Is there a better to test for a certain character than what is shown below?

    movf    chrin,w
    sublw    '+'
    btfsc    status, zero
    goto    isplus
    goto    notplus

Where chrin is the input data, status is the status register, zeor is the
zero flag bin in the status
register and the goto instructions are the locations for the handlers.  The
notplus can be
replaced by the habdler code.  chrin comes from an RS232 input.

Comments (good and bad) will be appreciated.

Regards to all,  Royce
