	TITLE	ASSPARM.SAL - ASSIGN  SYSTEM COMMAND LINE PARSER
;****************** START OF SPECIFICATIONS *****************************
; MODULE NAME: ASSGPARM.SAL
;
; DESCRIPTIVE NAME: Include the DOS system PARSER in the SEGMENT
;		    configuration expected by the modules of ASSIGN.
;
;FUNCTION: The common code of the DOS command line PARSER is optimized by
;	   the setting of certain switches that cause the conditional
;	   assembly of only the required portions of the common PARSER.
;	   The segment registers are ASSUMED according to the type .EXE.
;
; ENTRY POINT: SYSPARSE, near
;
; INPUT:
;	ES - has seg id of the SEGMENT
;	     that contains the input control blocks,
;	     defined below.
;
;	DI - offset into ES of the PARMS INPUT BLOCK
;
;	DS - has seg id of the SEGMENT
;	     that contains the DOS input COMMAND
;	     string, which is originally presented at 81h
;	     in the PSP.
;
;	SI - offset into DS of the text of the DOS input COMMAND string
;	     as originally presented at 81H in the PSP.
;
;	DX - zero
;
;	CX - ordinal value, intially zero, updated on each subsequent call
;	     to the value returned in CX on the previous call.
;
;	CS - points to the segment containing the
;	     INCLUDE PARSE.SAL statement
;
;	DS - also points to the segment containing the INCLUDE
;	     PARSE.SAL statement.
;
; EXIT-NORMAL:	Output registers:
;	 AX - return code:
;	    RC_No_Error     equ     0	 ; No error
;	    RC_EOL	    equ     -1	 ; End of command line
;
;	 DX - Offset into ES of the selected RESULT BLOCK.
;	 BL - terminated delimiter code
;	 CX - new operand ordinal
;	 SI - set past scanned operand
;
; EXIT-ERROR: Output registers:
;	 AX - return code:
;	    RC_Too_Many     equ     1	 ; Too many operands
;	    RC_Op_Missing   equ     2	 ; Required operand missing
;	    RC_Not_In_SW    equ     3	 ; Not in switch list provided
;	    RC_Not_In_Key   equ     4	 ; Not in keyword list provided
;	    RC_Out_Of_Range equ     6	 ; Out of range specified
;	    RC_Not_In_Val   equ     7	 ; Not in value list provided
;	    RC_Not_In_Str   equ     8	 ; Not in string list provided
;	    RC_Syntax	    equ     9	 ; Syntax error

;
;	 To assemble these modules, the sequential
;	 ordering of segments may be used.
