Can anyone help? I'm currently undertaking some research, as part of
my PhD, into determining the maintainability of COBOL programs.
However I need some COBOL programs to undertake some evalution of my
method. In particular, I'm after COBOL programs with all (or some) of
their versions and (the important bit) some indication of the effort
involved in applying maintenance to each version.

If you can help me with this, or would like to know some more about my
research then please contact me.

Regards,
Andrew.
