Problem:

Compatibility with Net Express v2.0 & v3.0

Resolution:

Release: 3.0   There's an online book called Migration Cookbook for some reference, regarding features that could have been omitted or changed from previous compilers (like Object Cobol, Workbench, Net Express 2.0 products).

However, we recommend that you recompile all your programs, initially, using REBUILD ALL.   Then when given new amended source codes/patches, just do a REBUILD for those files.   Only the parts of your project that have changed (including files that are dependent upon changed files) are rebuilt.
