;;       Include file containing structure definitions Shared Data Area
;;       for the Shared Data Area.
;;       The Shared Data Area contains data which is required by
;;       both the resident and transient KEYB code.  The Shared
;;       Data Area is allocated in the KEYBI2F file and will be
;;       resident following initial installation.

;; ;jwg  ; - Feb 1990 For 4.03.
;; ;AN007; -           Add Patriot/Sebring determination code for HOT Replug
;;                      so that INT 9 handler can alter keyboard Scan Code set.
;; ;M030                Merged IBM (Kermit - JP), KEYBOARD.SYS and KEYB.COM
;;                        versions of this file into one.

;; Translate Table Sections.  Both the Specific and Common
;; Translate Sections are formatted as follows.
;;
;; The Specific Translate Sections are chained together using the
;; XS_NEXT_SECT_PTR field (-1 if last section).
;; Translate Sections contains multiple States.
;; A State contains the translate tables for a single
;; shift state (IE lower case, upper case ....)
;; Each State may contain multiple translate tables.
;;
;; The Translate Section layout is defined using several STRUCs.
;; These STRUCs are allocated in the Shared Data Area as follows:
;;
;;       XLAT_SECT_STR            ; header info for the section
;;          STATE_STR             ; header for state #1
;;            XLAT_STR            ;   first translate tab for state #1
;;            XLAT_TYPE_1_STR or XLAT_TYPE_2_STR
;;            XLAT_STR            ;   second translate tab
;;            XLAT_TYPE_1_STR or XLAT_TYPE_2_STR
;;            ...
;;          STATE_STR             ; header for state #2
;;            XLAT_STR
;;            XLAT_TYPE_1_STR or XLAT_TYPE_2_STR
;;            ...
;;         ...
;;
;; A State may contain a "Set_Flag" table instead of translate tables.
;; These tables are used to set the NLS flags instead of generating
;; ASCII codes (for example: to remember dead key states).
;; There can be only on Set_Flag table per state.
;; The Set_Flag table layout is defined in the SET_FLAG_STR STRUC.
;;
;; So some states will contain translate tables (to generate ASCII codes)
;; and some states will contain a Set_Flag table (to record dead key
;; status).

;;    Type 1 = Table contains buffer entries only.
;;             Scan code is used as an index into xlat table
;;    Type 2 = Table contains pairs of SCAN/BUFFER_ENTRY.
;;             Table must be searched for matching scan.
;; Type 1 is the default.  Type 2 tables should be identified by setting
;; the TYPE_2_TAB bit in XLAT_OPTIONS.
;; Buffer entries default to 2-bytes per entry.
;; Optionally the table may contain ASCII codes only
;; (1-byte entries).  This is specified by setting the ASCII_ONLY bit
;; in XLAT_OPTIONS.  2-byte buffer entries are coded ASCII,SCAN.
