The Storage Management Subsystem of MVS/ESA, however, lets you bypass Access Method Services and define VSAM data sets using JCL. In contrast, you had to create a VSAM file using a utility program called Access Method Services.
Until the release of MVS/ESA, one of the important differences between VSAM and non-VSAM data management was that you could make most of the specifications necessary to create a non-VSAM file using standard JCL facilities. As a result, VSAM and non-VSAM data management facilities coexist on today's MVS systems. Unfortunately, VSAM was not able to meet all of a typical installation's data management needs.
