I'm encountering a strange bug hope someone could help. I have written a program using ibm's professional fortran (from Ryan-Macfarland). It works fine on an AT. But when I ran it on an XT it freezes in the middle. The machine has to be turned off to reboot. I tried to isolate where it freeze but discover that as I put in write statements the "point of freeze" also drifts. Running the program in a debugger (set break point before where it freeze, then run the rest with trace on) solves the problem! So much for isolating where it freeze. I tried throwing out all memory-resident programs and all device drivers. No help. I tried it on another XT, but same thing happened. I have 8087 in both XT. I'm running out on ideas (wish I have an 8086 emulator). If you have seen this bug and know how to fix it please let me know. Thanks. peter
