; MODECPRO.INC - INCLUDED BY MODECP.SAL
;****************** 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
; EFFECTS:
; INTERNAL REFERENCES:
; ROUTINES:
; MODECP - HANDLES ALL PROCESSING FOR THE CODEPAGE SUPPORT IN MODE
; SET_DEV_TYPE - SCANS LIST OF DEVICES FOR SPECIFIED DEVICE
; SET_GLOBAL_CODEPAGE - DEVICE IS "*", INVOKE OR QUERY GLOBAL CODEPAGE
; FUNCTION_SELECT - DETERMINES FUNCTION TO BE PERFORMED, DESIGNATE,QUERY,INVOKE
; DO_DESIGNATE - PERFORMS START DESIGNATE, DOWNLOAD FONT FILE, DESIGNATE END
; DES_START - HANDLES DETAILS OF START DESIGNATE FUNCTION
; DES_START_ERROR - DIAGNOSES ERRORS FROM DESIGNATE START
; MOVE_FILE - HANDLES DETAILS OF DOWNLOADING THE FONT FILE TO DEVICE
; DES_END - HANDLES DETAILS OF DESIGNATE END FUNCTION
; DO_INVOKE - HANDLES DETAILS OF INVOKE FUNCTION
; DO_STATUS - INTERROGATES DEVICE FOR CODEPAGE STATUS
; QUERY_ERROR - DISGNOSES ERRORS FROM QUERY REQUEST
; DISPLAY_CPID - DISPLAYS THE CODEPAGE ID AS PART OF STATUS REPORT
; SEND_MSG - SET UP ALL ERROR MESSAGES TO BE DISPLAYED
; QUEUE - HANDLES INTERFACE TO "PRINTF" FOR ALL MESSAGES
; EX_ERR - DOSCALL RESULTED IN CARRY, SO GO FIND OUT THE EXTENDED ERROR
; DO_GENERIC_IOCTL - PROCESS ALL GENERIC IOCTL CALLS TO THE DEVICE
;
; DATA AREAS:
; WORKAREA - Temporary storage
; EXTERNAL REFERENCES:
; ROUTINES:
; PRINTF - Uses the MSG parm lists to construct the messages
; on STDOUT, on on STDERR.
; DATA AREAS: A large buffer is allocated from free memory, if available.

; 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.
