; Microchip-style macros for SX Key
; by Al Williams (http://www.al-williams.com/awce.htm)
; V1.1 3 March 1999

; Notes: Use _W instead of W
;        Use _OPTION instead of OPTION

;        I've only tested this a bit -- let me know if you find mistakes.
; 	 NOP, CALL, SLEEP work without change
;        For the SX-only commands, use the SX mnemonics, or port over the stuff in
;          SXDEFS.INC
;        When you debug, the "hot spot" for the line is a blank line under the
;        actual line of code (because of NOEXPAND). You get used to this pretty quick. 
;        The upper window shows the SX mnemonics which is good for double checking my macros.

;        Don't like Microchip syntax? Don't use this file. Don't complain to me!

;        Get the most current copy at http://www.al-williams.com/awce.htm
;        While you are there check out our line of coprocessors (including floating point)
;        Work great with the PIC or SX chips
