                                   Purpose
                                   =======

CheckLastProc is mostly useful to software developers during testing of an
application.

This very small program has for purpose to check whether the last process
executed in a shell has correctly cleaned up after itself. If a problem is
found, it is corrected, an error message is printed, and the shell's failure
code is set to 5.

CheckLastProc currently checks whether or not the previous process deallocated
all of its signal bits, whether or not the previous process left hanging
Forbids, and finally whether or not the previous process left hanging
Disables. All conditions are corrected when they are detected.

The most practical use of this program is when it is included as part of the
shell prompt. That is, every time the prompt is displayed, CheckLastProc is
executed and ensures the previous process cleaned up after itself. Executing
this program from a prompt can be done under AmigaDOS 2.0 by declaring a
prompt string such as:

  Prompt "*`CheckLastProc*`> "

Several shells support this "program in a prompt" facility including the
AmigaDOS 2.0 shell, WShell and the ARP Shell. The AmigaDOS 1.3 shell
unfortunately doesn't.

This program can only be run from a shell.
