The 9.0 GA versions of Visual COBOL Development Hub and Visual COBOL are only compatible with one another; that is, you cannot use a patch updated version of Visual COBOL to compile using Visual COBOL Development Hub 9.0 GA. Incompatibilities result in the following error:
file doesn't support the "objlist" attribute
Conversely, incompatibility issues also exist in some circumstances when you attempt to use Visual COBOL 9.0 GA with a patch updated version of Visual COBOL Development Hub.
In either scenario, update the GA product to at least 9.0 patch update 1 to solve the incompatibility issues.
