SNAP was functionally stabilized more than 25 years ago, when it was decided to not enhance it to dump data space storage when data spaces were introduced in MVS/ESA SP3.1.0e. Some IPCS formatting code also runs under SNAP, so SNAP does inherit enhancements that code for free. But the code which is unique to SNAP gets almost no development attention, other than fixes to defects. Jim Mulder z/OS System Test IBM Corp. Poughkeepsie, NY
