   2         TITLE   COMPP.SAL - COMP SYSTEM COMMAND LINE PARSER
   3 ;****************** START OF SPECIFICATIONS *****************************
   4 ; MODULE NAME: COMPP.SAL
   5 ;
   6 ; DESCRIPTIVE NAME: Include the DOS system PARSER in the SEGMENT
   7 ;                   configuration expected by the modules of COMP.
   8 ;
   9 ;FUNCTION: The common code of the DOS command line PARSER is optimized by
  10 ;          the setting of certain switches that cause the conditional
  11 ;          assembly of only the required portions of the common PARSER.
  12 ;          The segment registers are ASSUMED according to the type .COM.
  13 ;          The Common PARSER is then INCLUDEd.
  14 ;
  15 ; ENTRY POINT: SYSPARSE, near
  16 ;
  17 ; INPUT:
  18 ;       ES - has seg id of the SEGMENT
  19 ;            that contains the input control blocks,
  20 ;            defined below.
  21 ;
  22 ;       DI - offset into ES of the PARMS INPUT BLOCK
  23 ;
  24 ;       DS - has seg id of the SEGMENT
  25 ;            that contains the DOS input COMMAND
  26 ;            string, which is originally presented at 81h
  27 ;            in the PSP.
  28 ;
  29 ;       SI - offset into DS of the text of the DOS input COMMAND string
  30 ;            as originally presented at 81H in the PSP.
  31 ;
  32 ;       DX - zero
  33 ;
  34 ;       CX - ordinal value, intially zero, updated on each subsequent call
  35 ;            to the value returned in CX on the previous call.
  36 ;
  37 ;       CS - points to the segment containing the
  38 ;            INCLUDE PARSE.ASM statement
  39 ;
  40 ;       DS - also points to the segment containing the INCLUDE
  41 ;            PARSE.ASM statement.
  42 ;
  43 ; EXIT-NORMAL:  Output registers:
  44 ;        AX - return code:
  45 ;           RC_No_Error     equ     0    ; No error
  46 ;           RC_EOL          equ     -1   ; End of command line
  47 ;
  48 ;        DX - Offset into ES of the selected RESULT BLOCK.
  49 ;        BL - terminated delimiter code
  50 ;        CX - new operand ordinal
  51 ;        SI - set past scanned operand
  52 ;
  53 ; EXIT-ERROR: Output registers:
  54 ;        AX - return code:
  55 ;           RC_Too_Many     equ     1    ; Too many operands
  56 ;           RC_Op_Missing   equ     2    ; Required operand missing
  57 ;           RC_Not_In_SW    equ     3    ; Not in switch list provided
  58 ;           RC_Not_In_Key   equ     4    ; Not in keyword list provided
  59 ;           RC_Out_Of_Range equ     6    ; Out of range specified
  60 ;           RC_Not_In_Val   equ     7    ; Not in value list provided
  61 ;           RC_Not_In_Str   equ     8    ; Not in string list provided
  62 ;           RC_Syntax       equ     9    ; Syntax error
