Lines: 11 I have a program compiled by Microsoft C using the switch /AL (large memory model). It terminated normally in the past. Recently, I got more RAM so I put himem.sys in config.sys. Then I got unexpected errors, sometimes infinite loops, sometimes floating point math errors. I tried the debugger CodeView. My program has no runtime error under CodeView no matter himem.sys is in effect or not. Any suggestions? Ming Ouyang ouyang@paul.rutgers.edu
