    EDITEL

    EDITEL is a screen editor/code generator for GnuCOBOL programmers

    One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a...
