CHANGES TO DEMO.MAC

The following new features have been added to DEMO.MAC:

 o System utilization statistics for the current time increment and
   since startup.  The since startup statistics will only be displayed
   if the system has the floating point processor hardware.  The task
   build command file must be changed to include the '/FP' switch.  This
   feature is not available on VT05 and VT50 terminals.

 o The task naming convention has been changed.  All '...' and '$$$'
   tasks are displayed as the task name and the terminal number.  For
   example the task '...PIP' running from TT23: will be displayed as
   PIPT23 and if it is running from BA0: it will be displayed as PIPB0.
   Pure areas and SGA's will not be renamed.

 o Tasks waiting for memory (including tasks checkpointed) are displayed
   in two columns at the far right of the display.  The amount of memory
   needed by these tasks is also displayed.

 o The display header (the first three lines) has changed to include
   the number of errors since startup, the total uptime and the number
   of currently active jobs.  If DEMO is run as a real time task the
   currently active task will be displayed instead of the active job
   count.

 o Two new display commands have been added.  The 'T' command will set
   the top address of the display.  The 'R' command will reset the display
   to what is was when DEMO was first run.  The syntax checking for all
   commands has been enhanced so that if an illegal value is typed it
   will be rejected.

 o Two values may be patched at task build time to set the initial screen
   granularity and bottom of display memory.  The memory locations are:

	$MEMST - start of memory in K words
	$GRAIN - column granularity in 32. word blocks

   The next 'E A', 'B', 'T' or 'G' may change these values.  The 'R'
   command will reset the display to these values.  A value of zero means
   that the parameter is unspecified and DEMO will calculate it.

 o A string of exclamation marks '!' will indicate the end of memory on
   the display.
