The control C handler address is at INT 23h. There are also serveral
addresses stored in the programs PSP. If you spawn a program without
executing it, you can modify the terminate address, control c address
and hard error address. Once the modifications have been made you can
then let the program execute. When the program terminates, dos returns
control to these addresses. This is a much easier method of traping
program termination then traping the interupt.
Anyway, I wrote a structure of the contents of the PSP. If there is
enough interest, I will post it.
