Bob, Does your problem have anything to do with dynamic allocation of GDG's?
We also discovered a change in behaivor in dynamic allocation as we migrated to z/OS 1.11. Our situation was related to using SVC99 to allocate GDG datasets, the code was placing the entire dataset name including relative generation number (i.e. 'DATA.SET.NAME(0)' ) in the dataset name text unit. Under 1.11 it became evident that although the allocation worked and the dataset was able to be opened and written to, there was no ENQUE issued for DATA.SET.NAME.G000V00. According to the FM's this shouldn't work, when using relative generation number, it needs to be placed in the member name text unit. IBM was unwilling to investigate the change in behavior since we came from an unsupported release...
