List of pseudo mnemomics understood by MPASM

The latest MPASM/MPLAB User's Guides contain a
table showing this and all other pseudo-ops understood by MPASM;

Call across page boundary  LCALL k     BCF 3,5 or BSF 3,5
                                       BCF 3,6 or BSF 3,6
                                       CALL     k

By the way, don't bother using the "LCALL" pseudo-op... Since it
doesn't restore the code-page bits after the CALL, it's sorta
useless.  Also, be careful with the pseudo-ops that assemble to two
instructions; constructs like the following, for instance, will cause
you great pain and suffering:

    ; DON'T DO THIS!

    BTFSS   FLAGS,SWITCH    ;If the switch is pressed, skip ahead.
    NEGF    REG             ;Otherwise, negate the REG register.

Thanks a lot! A consultant my former employer hired used BZ and BNZ extensively. I have also been using them as well, but I didn't know where they came from and I wanted to know if there were any more of them. Also, I needed to be sure that they would reliably work. This posting helped me. Thanks a lot!
