    The DTC program provides an on-line appointment scheduler and calendar     
facility. The program has three display commands, D/W/M for Day-/Week-/      
Month-At-A-Glance, plus alternate-display and schedule-file maintenance          
commands. It is invoked by:                                                      
    DTC [[command] [date]].                                                     
    If no command is given, the DTC command menu is displayed. Commands are     
then requested and processed until the user types Q (quit), EX (exit), or ^Z.   
    The date format is mmddyy for Day and Week, and mmyy for the month part.     
The command "D 052785" displays appointments for May 27, 1985. The command:     
"9:00 <appointment string>" would insert the appointment specified by          
"appointment string" at 9 AM on the default date. The default date is the last 
date given unless the I command is used to reset to today's date. Dates may be  
given as mmddyy, mm/dd/yy, or dd-mmm-yy, or reasonable subsets (i.e, "D 5"      
shows appointments for the fifth of the current month, "M 7/86" is July 1986).  
Time entries of the form hh:mm>hh:mm specify ranges. A CLI command to enter an  
appointment might be (quote is used to preserve lower-case, no final quote):   
     1>DTC "D 041585 9:00 Income Tax due tonight                                  
Indirection:                                                                     
    Entries in the DTC file of form "999999080 dir/filename.typ=" point at the   
filename and the S or G cmds enter appts. in them, other cmds read them. Use   
the F cmd to change files. DTC commands T, C, and R correspond to D, M, and W   
but exit after one display. More info in DTC.MEM.
