	TITLE	XCOPYPAR.SAL - LOOK AT COMMAND LINE PARMS
;****************** START OF SPECIFICATIONS *****************************
; MODULE NAME: XCOPYPAR.SAL
;
; DESCRIPTIVE NAME: Handle the definition of the DOS command line parameters
;		    and the interface to the DOS system PARSER.
;
;FUNCTION: The static data areas are prescribed by the DOS system PARSER
;	   to define the several parameters presented to XCOPY.  These
;	   data areas are passed to the PARSER, and its responses checked
;	   to determine the nature of the user's specifications.  Any errors
;	   found in the user's parameters are defined in messages back
;	   to the user.
;
; ENTRY POINT: PARSER, near
;
; INPUT: (DOS COMMAND LINE PARAMETERS)
;
;	      SOURCE OPERAND:			   TARGET OPERAND:
;
;	      [d:] [path] filename[.ext]	   [d:] [path] [filename[.ext]]
;		or
;	      [d:] path [filename[.ext]]
;		or
;	      d: [path] [filename[.ext]]
;
;	 WHERE
;
;	      [d:] - To specify the Source drive
;
;	      [d:] - To specify the Destination drive
;
;
;	      SWITCHES:
;
;	      /A /D /E /M /P /S /V /W
;
;
;	Upon entry to PARSER in this module,
;	"CURRENT_PARM" = offset to start of parm text in command string
;	"ORDINAL" = initialized to zero
;	PSP+81H = text of DOS command line parms string

; EXIT-NORMAL:

; EXIT-ERROR:

; INTERNAL REFERENCES:
;    ROUTINES:
;	PARSE_ERROR:NEAR Display the appropriate Parse error message.

;    DATA AREAS:
;	The several parameter control blocks, defined by the System
;	PARSER interface, defining the XCOPY parameters.

; EXTERNAL REFERENCES:
;    ROUTINES:
;	SYSPARSE:NEAR	System Command Line Common Parser.
;
;    DATA AREAS:
;	EXITFL:BYTE	Errorlevel return code.
;	MSGNUM_PARSE:WORD Message descriptor for all parse errors.
;
; NOTES:
;	 This module should be processed with the SALUT preprocessor
;	 with the re-alignment not requested, as:
;
;		SALUT XCOPYPAR,NUL
;
;	 To assemble these modules, the alphabetical or sequential
;	 ordering of segments may be used.
;
;	 For LINK instructions, refer to the PROLOG of the main module,
;	 XCOPY.SAL.
;
; REVISION HISTORY: A000 Version 4.00: add PARSER, System Message Handler,
;			 Ignore unique volume serial number differences
;		    A004 PTM0700 9/02/87 Avoid duplicate switches and
;			 display parm in error.
