Look on page 62 of _Programmer's Guide to the IBM PC and PS/2_: In the PC/XT/AT family, the 16 bytes starting at 0040:00F0 are reserved as an intra-application communication area (ICA). Norton also gives a warning that some versions of the _IBM PC Technical Reference Manual_, through a typographical error, list the address as 0050:00F0. Rick "Any questions? Any answers?
