Program Force (FRC) 

This will program is modeled after the RSTS/E Utility command, FORCE.
It enables a privileged user to effectively type on another terminal
on the system, using his own terminal.  For example, typing: 

FRC TT16:HELLO 

terminated by a carriage return, would cause the system to behave as
if the string HELLO followed by a carriage return, were actually typed
on terminal TT16:. 

A special character to FORCE is the uparrow (^).  An uparrow means
that the following character should be forced as a control character. 
For example, typing: 

FRC TT16:^Q 

terminated by a carriage return, would be the same as if a control-Q
and a carriage return were typed on TT16:.  Two uparrows in a row
force an uparrow.  It is currently not possible to force a control
uparrow. 

If the FRC command line to the CLI (Command Line Interface, DCL or
MCR) is terminated with a carraige return, the carriage return is also
forced to the target terminal.  If the command line is terminated by
an escape character, the escape is not forced.  Therefore, using the
escape, it is possible to force without a trailing carriage return. 

A characteristic of RSX indirect command files is that CLI command
lines are executed as if they had been typed terminated by an escape.
This means that when using FORCE from an indirect command procedure,
no carriage returns will be forced unless there explicitly in the form
of an ^M.  For example, here is an indirect command file for starting
Word-11 spoolers: 

.ENABLE QUIET
.ENABLE SUBSTITUTION
.SETS TT "TT16:"
FRC 'TT'HEL PENNER^M
.DELAY 3.S
FRC 'TT'PASSWO^M
.DELAY 3.S
FRC 'TT'WORD11^M
.DELAY 3.S
FRC 'TT'U^M
.DELAY 5.S
FRC 'TT'AD^M
.DELAY 3.S
FRC 'TT'TT5:^M
.DELAY 3.S
FRC 'TT'FORCE^M
.DELAY 3.S
FRC 'TT'^M
.DELAY 3.S
FRC 'TT'^M
.DELAY 3.S
FRC 'TT'AD^M
.DELAY 3.S
FRC 'TT'TT6:^M
.DELAY 3.S
FRC 'TT'FORCE1^M
.DELAY 3.S
FRC 'TT'^M
.DELAY 3.S
FRC 'TT'^M
.DELAY 3.S
FRC 'TT'^M
.DELAY 5.S
FRC 'TT'F^M
.DELAY 3.S
FRC 'TT'LOG^M
.DELAY 3.S

the delay directives are to allow Word-11 time to execute each
command. 

Finally, the MCR dispatcher, the part of RSX that invokes FORCE,
automatically converts tabs to a single space, removes trailing
blanks, upcases, etc....  Therefore, it is currently not possible to
force lowercase characters.
