Hi,
a very easy way to work with excel is using the format SYLK with the extension SLK. It is ASCII so it is easy to read, write, etc. It has almost all functionality of the complete worksheet. Only some minor things are not within the SYLK standard but that can not be a problem. Also a little macro in Excel can solve those small problems.
Also: the SYLK format is up- and downwards compatible. Unbelievable? Yes, almost. But I can read on my very old Tandy TRS80 model 100 with an Excel ROM in it (I bought it in 1984/5), the SYLK output from a current Excel version. Of course, not all functionality is there but what it can understand, it does. The current Excel program understands perfectly the old SLK files. No problem.
Also: save as SLK and start your COBOL program, wait for it to finish and reload the SLK can be in Office Basic/VBA/macro's.
Give it a try. You will like it.It is easy and also version independent!
