TCF - Terminal Control Functions
		================================

			Users' Guide
			============

 TCF is a very simple task to allow you to control the characteristics
 of your terminal.  TCF must be installed and is then executed by

	TCF n1,n2,n3...

 where  n1,  n2,  n3...  are  octal  numbers.  TCF merely converts the
 numbers and outputs the relevant binary codes in a string.  Thus, for
 example,

	TCF 30

 will output an octal 30 to the requesting screen, which will clear it
 (if it is a SYSTIME MKII or MKIII).
 This can most usefully be used in commandfiles to ensure the terminal
 is in a defined state at various points.


 TCF can report two possible errors:-

 1.  SYSTEM DIRECTIVE FAILURE

     This  means  that  TCF was not run in the correct manner, and TCF
     could not retrieve the MCR commandline.

 2.  NON-OCTAL VALUE

     This  means that some character other than a valid octal digit or
     a comma was specified on the commandline.

 TCF simply gets the input commandline from MCR, scans it from left to
 right converting each octal number into a binary value in an internal
 buffer,  and  then  outputs  that  buffer  to  the  screen.   It is a
 non-privileged  task,  with  a taskname of ...TCF which uses one unit
 (which  must  be assigned to TI:).  It is also recommended that it be
 given a priority above 50.
