+        TITLE   DCOPYSM.SAL - DISKCOPY SYSTEM MESSAGES
+;****************** START OF SPECIFICATIONS *****************************
+; MODULE NAME: DCOPYSM.SAL
+
+; DESCRIPTIVE NAME: Include the DOS system MESSAGE HANDLER in the SEGMENT
+;                   configuration expected by the modules of DISKCOPY.
+
+;FUNCTION: The common code of the DOS SYSTEM MESSAGE HANDLER is made a
+;          part of the DISKCOPY module by using INCLUDE to bring in the
+;          common portion, in SYSMSG.INC.  This included code contains
+;          the routines to initialize for message services, to find
+;          where a particular message is, and to display a message.
+
+; ENTRY POINT: SYSDISPMSG:near
+;              SYSGETMSG:near
+;              SYSLOADMSG:near
+
+; INPUT:
+;    AX = MESSAGE NUMBER
+;    BX = HANDLE TO DISPLAY TO (-1 means use DOS functions 1-12)
+;    SI = OFFSET IN ES: OF SUBLIST, OR 0 IF NONE
+;    CX = NUMBER OF %PARMS, 0 IF NONE
+;    DX = CLASS IN HIGH BYTE, INPUT FUNCTION IN LOW
+;   CALL SYSDISPMSG             ;DISPLAY THE MESSAGE
+
+;    If carry set, extended error already called:
+;    AX = EXTENDED MESSAGE NUMBER
+;    BH = ERROR CLASS
+;    BL = SUGGESTED ACTION
+;    CH = LOCUS
+; _ _ _ _ _ _ _ _ _ _ _ _
+
+;    AX = MESSAGE NUMBER
+;    DH = MESSAGE CLASS (1=DOS EXTENDED ERROR, 2=PARSE ERROR, -1=UTILITY MSG)
+;   CALL SYSGETMSG               ;FIND WHERE A MSG IS
+
+;    If carry set, error
+;     CX = 0, MESSAGE NOT FOUND
+;    If carry not set, ok, and resulting regs are:
+;     CX = MESSAGE SIZE
+;     DS:SI = MESSAGE TEXT
+; _ _ _ _ _ _ _ _ _ _ _ _
+
+;   CALL SYSLOADMSG              ;SET ADDRESSABILITY TO MSGS, CHECK DOS VERSION
+;    If carry not set:
+;    CX = SIZE OF MSGS LOADED
+
+;    If carry is set, regs preset up for SYSDISPMSG, as:
+;    AX = ERROR CODE IF CARRY SET
+;         AX = 1, INCORRECT DOS VERSION
+;         DH =-1, (Utility msg)
+;       OR,
+;         AX = 1, Error loading messages
+;         DH = 0, (Message manager error)
+;    BX = STDERR
+;    CX = NO_REPLACE
+;    DL = NO_INPUT
+
+; EXIT-NORMAL: CARRY is not set
+
+; EXIT-ERROR:  CARRY is set
+;              Call Get Extended Error for reason code, for SYSDISPMSG and
+;              SYSGETMSG.
