;	asm(1.0) macro package - Various defines/macros that
;	may be found useful.
;
;	This macro package has been written and placed in the
;	public domain by Douglas J Leavitt, 1986.  This macro
;	package is based on Commodore-Amiga header files printed
;	In The ROM Kernel Manuals, published and printed by
;	Commodore-Amiga, and Addison-Wesley publishing.
;
;	The goal of this macro file is to be upwardly compatible
;	with the include file of the same name.
