To build probe:

It is reccomended that you check Probe's source, to make sure it doesn't have
any obvious incompatabilities with your system (its use of Global Event Flag
52, or the clock ector address on your system). Then PROBE.CMD will build it
for you. SEF.CMD works the same way.




	Probe's output is in the following format:
-------------------------------------------------------------------------------
TASK: <active task, blank if none active on last sample>
INTTIM: <clock ticks occurring while PR7 non-zero (some interrupts locked out)>
SYSTIM: <clock ticks other than above with processor in Kernal mode>
USRTIM: <clock ticks ocurring during execution in User mode>
NULTIM: <clock ticks occuring when processor was in wait loop>
TOTAL #		NOT COUNTED: #
TaskA #   TaskB #   TaskC #  ...
SubA1 #   SubB1 #   SubC1 #
SubA2 #   SubB2 #   SubC2 #
SubA3 #		    SubC3 #
SubA4 #
.
.
.
-------------------------------------------------------------------------------
Tasks are not sorted and the ones displayed are the first K tasks caught 
executing, where K is the maximum number of tasks Probe was built to monitor.
The subroutines for each task are displayed in a some-what sorted order, the
higher the number of samples charged to them, the higher they tend to rise in 
the list. Task B is shown above with only two subroutines with any counts 
charged against them. "TOTAL" refers to the total number of samples 
taken. "UNCOUNTED" refers to count for which no specific subroutine was 
charged.




	To use Probe:

Install and run Probe. It is now in "stasis" mode, and it is OK to abort it 
when in that mode (It has nothing allocated in the pool space). To start the 
display, set the global event flag. To stop/clear the display, clear the event 
flag. A small FORTRAN utility (SEF) is provided for this purpose (When SEF is 
installed as ...CEF it clears the specified event flag. When SEF is installed
as ...REF it displays the status of the specified event flag. As ...SEF it sets
it.), although any method as setting the event flag probe was built to use will
work.
