; Module Function
; ***************
;	This module provides the operating system interface addresses for
; subsequent system functions.  They are placed in a seperate module and
; declared to be PUBLIC so that they may be used by any other module that 
; referances them as EXTERNAL.
;	Placing all Global equates in a seperate file is not required by
; the assembler or linker but is generally good programming practice and
; allows corrections, or additions, to be easily made to all files that
; referance these values.
;	Note that while all relocating assembler/linkers will accept and
; relocate word values (16 bits), many will generate errors if byte values
; (8 bits) are referanced.
