;****************** START OF SPECIFICATIONS *****************************
; MODULE NAME: MODECP

; DESCRIPTIVE NAME: MODE, CODEPAGE HANDLER

;FUNCTION: Manages the codepage file, sending it to the
;	   device when a DESIGNATE is requested, telling
;	   the device which FONT to select when ACTIVATE
;	   is requested, and displaying the font status
;	   of the device when QUERY is requested.

; NOTES:
;	 This module should be processed with the SALUT pre-processor
;	 with re-allignment not requested, as:

;		SALUT MODECP,NUL,;


; ENTRY POINT: MODECP
;    LINKAGE: CALL MODECP

; INPUT: As defined by the "CODEPAGE_PARMS" STRUC.
;	All four segregs are expected to point to the one common
;	segment, called PRINTF_CODE.

; EXIT-NORMAL:	ERRORLEVEL 0 - Successful completion

; EXIT-ERROR: ERRORLEVEL 1 - An error message is also displayed

;  AX001 - P3976: Need to have all pieces of messages in MODE.SKL so have to
;		  implement the SYSGETMSG method of getting addressability to
;		  the pieces.  This means that the code does a SYSGETMSG call
;		  which returns a pointer (DS:SI) to the message piece.  The
;		  address is then put in the sublist block for the message
;		  being issued.

;  AX002 - P4576  Segments were being trashed before calling message services
;		  because device type was wrong on IOCTL call because ES was
;		  zero when using CMPSB in SET_DEV_TYPE and no match was made.
