I haven't had any messages from the list for two days so I don't
know if anyone caught the error (or even got the previous post which
may have been inadvertently duplicated - sorry).

   ;Subtract two byte literal.
   ;At exit, C = 0 if result is negative

sub_word_literal: macro aaa, lll

   movlw   low (~lll + 1)
   addwf   aaa+1, f
   movlw   high ((~lll + 1) & h'ffff')
   skpnc
   addlw   1
   skpnc
   skpz
   addwf   aaa, f
   endm

There must be a better way!
