Instant Interrupts and STRINGS-16.PBP in the same program

Here's the right one.

Oh, that helps even more.

There is a conflict between the two programs.
DT_INTS also has a GetAddress macro.

So you can just delete the GetAddress macro in the main program.

Don't forget to un-comment the include files.

See, now why can't "SHE" ever grasp that concept.
But that's another story.

Great! Hope the rest of the program works out too.
