Release ANTMAIN's enqueue on a WSDS. The command releases the enqueue on a WSDS by marking the WSDS as unavailable for new operations, and releasing the WSDS after the current operations complete. Parameter llq is the last qualifier of the dataset to be released, for non-VSAM data sets. For VSAM data sets, parameter llq is the last qualifier of the CLUSTER component of the data set. The DATA component is then selected for release automatically. For example, F ANTMAIN,RELEASEWS FCWK0004 releases work data set 4, either immediately if the data set is not in use, or at completion of all jobs using its space.
