Hi,
If you go to Darrel's website and download the .zip file for DT_INTS-14 you get two (2) files. One is called DT_INTS-14.bas and the other is called ReEnterPBP.bas. In your program you are correctly icluding DT_INTS-14.bas but you are, incorrectly trying to include a file called ReEnterPBP-14.bas - your code:
Code:
INCLUDE "DT_INTS-14.bas"     ; Base Interrupt System          emp
INCLUDE "ReEnterPBP-14.bas"   '<-----Here, you have the wrong filename.
See, the file your're TRYING to include is ReEnterPBP-14.bas but the file is called ReEnterPBP.bas (if you haven't renamed it in which case I don't what the problem is).

/Henrik.
