As refer to the subject above, I've a software which I need to add in
new task, without modifying the existing code. So,would it possible to
control a software execution whereby at specific instruction, it will
transfer the control to another exe? My idea sofar is to write an exe,
eg. D.exe, that behave like a de *** and it will started to 'debug'
the A.exe. Then when at specific instruction in the A.exe, it will
transfer the control to D.exe. Now, the D.exe will perform some tasks
and when it's done, it let A.exe to proceed. Thought this can be done
by setting the trace bit in the flag register to 1, and then stop the
'tracing' of A.exe where the D.exe need to perform the extra task.
Pls advice and appreciate any feedback.
