2 weeks ago I migrated our production systems from W4GLv2 to OpenROAD. We use
UNIX (Solaris 2.4) and Ingres 6.4. We have 7 main applications with 600K lines
of
4GL code.

The only code changes required were to remove some # symbols present in some of
our code.

The screens had to be re-arranged as the size of buttons and entry fields had
changed and overlaps occurred. I had to create a colour table to customise the
colours we used in version 2. The standard OpenROAD colours were terrible.

Once all that was done, everything worked fine. All our calls to C routines
worked, operating system calls, dynamic 4GL processing we do all worked with no
problems. The migration went very smoothly and easily.

Hope this helps some.
