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