Links to Programming Resources

In no particular order, here are some links to other web sites or resources in the general area of computer programming. You should be warned that they will be slanted toward COBOL and IBM Mainframe subjects, but not limited exclusively to those areas. There are also links to C/C++, Visual Basic, X86 Assembler, Linux, REXX, ISPF, text editors, and TN3270 Terminal Emulators.
