    For those that have tried to use these, note that they are presently CVF

    Compiler-specific versions will be posted as/if required once the design
    is settled. The final release will be limited in capability and quite
    focused on "console" functions as you can get more sophisticated GUI
    functions via other tools (some free and some not). For now, I'm
    interested in what would be considered the MINIMUM set of routines
    required. The most frequent difficulty I recall is inability to perform
    an edit write (set current position and overwrite). No input routines
    are presently included. I assume hot key read, line read, and read
    character at cursor position would be desirable.
