+        TITLE   DCOMPP.SAL - DISKCOMP SYSTEM COMMAND LINE PARSER
+;****************** START OF SPECIFICATIONS *****************************
+; MODULE NAME: DCOMPP.SAL
+;
+; DESCRIPTIVE NAME: Include the DOS system PARSER in the SEGMENT
+;                   configuration expected by the modules of DISKCOMP.
+;
+;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 .COM.
+;          The Common PARSER is then INCLUDEd.
+;
+; 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.ASM statement
+;
+;       DS - also points to the segment containing the INCLUDE
+;            PARSE.ASM 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
+;

+;    ROUTINES: SYSPARSE:near (INCLUDEd in PARSE.ASM)
+;
+;    DATA AREAS: none
+;
+; EXTERNAL REFERENCES:
+;    ROUTINES: none

+; NOTES:
+;        This module should be processed with the SALUT preprocessor
+;        with the re-alignment not requested, as:
+;
+;               SALUT DCOMPP,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,
+;        DISKCOMP.SAL.
