Privileged Commands
commands). If we want to look at information in another PIN's PCB, or our own, we
can use the PCB option on the D command.
In this example, we are looking at the PCB for PIN 265, starting at byte offset 8 for two
16-bit words. Byte 8 has the starting priority, and byte 9 has the current priority. Bytes
10 and 11 make up a 16-bit word that contains the PIN. Note that the PIN matches the
one we entered.
We have the example program running as PIN 265 in the same processor. The
program has a breakpoint at the end of the EXAMPLE_FILL_ARRAY procedure. First,
we look at the breakpoint table.
With the privileged mode enabled, we can see breakpoints to all the processes. Thus,
while running PIN 10, we also see PIN 265's breakpoint.
V Command
We can use the V command to view and manipulate information for another PIN. In
this example, we vector to PIN 265. We use the ? command to see the environment
before and after the V command has been entered.
