APPT Appointment Minder
Program History:

Version 1.00    23 Oct 92        
        Initial release.

Version 1.01    12 Nov 92        
        Minor update for 8086/88 compatability.

Version 1.10    30 Nov 92        
        Corrected buffer-overwrite problem that occurred with files > 4608 
        bytes.  APPT now clears file buffer before writing.

Version 1.20    07 Jul 93        
        Added environment option so that APPT can find APPT.DAT and APPT.BAK 
        wherever they reside.  Consequently, this requires more error-checking.
        The word "TypeOver" now appears on-screen when registered users are 
        editing in such mode.  Enhanced registration procedure and code 
        efficiency.  Added utilities SETERROR, HOLDTIME and ALLBUT as separate
        files.

Version 1.21    01 Aug 93
        Bug-fix--corrected forced use of environment variable.

Version 1.30    01 Jan 94
        Added international switch (/I) to allow DD-MM date format.  Added
        log switch (/L) to allow APPT to log past appointments in APPT.LOG.
        Added color switch (/Cnn) to allow user to determine APPT's display
        color.  Consequently, included color codes as appendix in APPT.DOC.

                        SNYTAX: APPT [/I] [/L] [/Cnn]

        Exiting APPTEDIT with [Esc] now automatically saves edits; [Alt][Q] 
        discards edits.  Registered username is displayed on-screen.  APPT
        now indicates by an * in the menu bar that the data have been 
        modified.  "TypeOver" appears for all users.  Enhanced code efficiency.
