U.C. San Diego Lines: 14 Does anyone have any experience controlling I/O directly from UCSD Pascal on an IBM-PC? I want to manipulate an AST board from a Pascal program, but cannot figure out what statement(s) to use. The normal trick of using a pointer to map to the memory/io space only works on micros with a memory-mapped i/o structure. Are there any special functions available? Or does anyone know how to write functions in assembly language which are compatible with Pascal function calls? John Van Zandt UCSD ucbvax!sdcsvax!jvz
