This sample shows two executions of EXEHDR. The first is using the normal
verbose listing option. Note that the imported function list is difficult
to figure out because of cardinal numbers, such as DOSCALLS.5.
The second execution of EXEHDR is filtered thru IMPFILT to decode the
cardinal numbers. You can verify that DOSCALLS.5 is DOSEXIT.
The undocumented function DOSQPROCSTATUS (DOSCALLS.154) is listed. It
turns out, using CodeView, that this is the system call which provides
all the status information for the PSTAT command.
