PAGE ,132 ; TITLE COMPP.SAL - COMP SYSTEM COMMAND LINE PARSER ;****************** START OF SPECIFICATIONS ***************************** ; MODULE NAME: COMPP.SAL ; ; DESCRIPTIVE NAME: Include the DOS system PARSER in the SEGMENT ; configuration expected by the modules of COMP. ; ;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 ; ; INTERNAL REFERENCES: ; ROUTINES: SYSPARSE:near (INCLUDEd in PARSE.ASM) ; ; DATA AREAS: none ; ; EXTERNAL REFERENCES: ; ROUTINES: none ; ; DATA AREAS: control blocks pointed to by input registers. ; ; NOTES: ; This module should be processed with the SALUT preprocessor ; with the re-alignment not requested, as: ; ; SALUT COMPP,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, ; COMP1.ASM. ; ; REVISION HISTORY: A000 Version 4.00: add PARSER, System Message Handler, ; Add compare of code page extended attribute, if present. ; ; COPYRIGHT: "The DOS COMP Utility" ; "Version 4.0 (C)Copyright 1988 Microsoft" ; "Licensed Material - Property of Microsoft" ; ;PROGRAM AUTHOR: DOS 4.0 Edwin M.
