CBT Tape Home Page - MVS Freeware

Dec 22, 2024 - See the first note about the Updates page

ALWAYS CHECK HERE FOR THE LATEST VERSIONS OF FILES: All file updates are ONLY applied to the UPDATES page until a new tape version is cut. Please check the UPDATES page to see if your FILE NUMBER has been updated since the last "Version Cut" of the CBT Tape. If your file number is NOT on UPDATES, ONLY THEN should you download it from the CBT subdirectory. Don't download a back-level file unnecessarily.
