Does CA Datacom support allocating large format sequential data sets greater than 65,535 tracks with DSNTYPE=LARGE?

Environment

Component:

Resolution

Yes, CA Datacom supports the use of large format sequential data sets which can be larger than 65,535 tracks  (4369 cylinders) per volume. 

You allocate a large format data set by using the DSNTYPE=LARGE parameter on the DD statement in the JCL. 

However, extended format data sets defined with DSNTYPE=EXT, DSNTYPE=EXTREQ or DSNTYPE=EXTPREF  are not supported because they cannot be accessed using the EXCP access method which is used by CA Datacom.
