INTS will show you the contents of the zero-page interrupt vectors on a
PC or clone. It will print a list of the interrupt numbers, with the
associated segment:offset addresses. If the vector contains a zero, that
interrupt will not be displayed. If it is non-zero, the first location
of the interrupt service routine is examined, and if it is an IRET (interrupt
return) instruction, then "--> IRET" is printed next to the address.
All values are printed in hexadecimal.
The most common use of this routine is to determine which interrupts a TSR
is stealing. To do this, run ints with and without the TSR loaded, directing
output into files, then compare the two files.
Glancing thru the code now, I see some things that might be redundant, but
it works, so I'm not going to fix it.
Constructive comments are welcome.
