I recently did a z/VSE to z/OS conversion. There were assembler programs
that were not recompiled in 50 years. Yes, fifty years. They were still
running. Also, they were written to use ISAM and they were currently
using the ISAM transparency feature of VSAM to read/write KSDS file.

Impressed with the depth on this list from the contributors. I am getting back
into the z-series software and application development after years of being in
another domain.
Here is a very broad question: when you guys/girls are moving your app
portfolio from one hardware platform to another (say, z14 to z15), to what
extend are the apps compatible with the new platform without recompilation?
