;Note:
; - The MATCH_FLAG is bit significant. You can set, for example, TIME bit and
; DATE bit simalteniously.
;
; The parser examins each bit along with the following priority.
;
; COMPLEX -> DATE -> TIME -> NUMERIC VAL -> SIGNED NUMERIC VAL -> DRIVE ->
; FILE SPEC -> SIMPLE STRING.
;
;
; - When the FUNCTION_FLAG is 0001 or 0002, the STRING pointed to by a pointer
; in the result buffer is capitalized.
;
; - Match_Flags 0001H and 0002H have meaning only for the positional.
;
;
; - The "...",0 (bottom most line) does require '=' or '/'. When you need a
; switch, for example, '/A', then STRING points to;
;
; DB 1 ; number of following synonyms
; DB '/A',0
;
; When you need a keyword, for example, 'CODEPAGE=', then "...",0 will be;
;
; DB 1 ; number of following synonyms
; DB 'CODEPAGE=',0
;
;
; - "..." must consist of upper case characters only because the parser
; performs pattern matching after converting input to upper case (by
; using the current country upper case table)
;
;
; - One "..." can contain only one switch or keyword. If you need, for
; example /A and /B, the format will be;
