We have a pdp-11/23 with RT-11 running on it (That is what it came with). We recently got OSMI Pascal but it does not interface to the machine as well as we need. I am not thrilled about programming in MACRO-11 so where can I get a C real cheap? Oh, our RT-11 is version 4.0 Tim Giebelhaus stolaf!umn-cs!minn-ua!tim
