CBT Tape Downloads

V509 Final Version — Jul 07, 2025

The files are all packaged with PKZIP and are in EBCDIC so you download from here, unzip, upload as Binary (No EBCDIC to ASCII translation) to your mainframe to an FB80 data set.

Sequential files are suffixed .DATA and are ready to use after being uploaded (again as Binary). File 1 through 5, and 7, are the only files always not packaged with XMIT. Files suffixed .XMI are in XMIT format so you will need to do a TSO command RECEIVE INDATASET(???) where ??? is the file you upload to transform it back to usable PDS or sequential file.

You will need a utility to unzip (decompress) the .ZIP files. Suggested options: 7-Zip (free), WinZip, or RAR.

For latest versions of files that have been updated since the last tape version, please check the Updates page. It is advisable to check the Updates page BEFORE you check this page for the file number that you want, just to make sure you get the latest version of the code.

Need more help? Having Trouble? See our download instructions.

File 1 on both the CBT and Overflow (COV) is a complete index and guide to what is on the tape so if you do not already have file 1 for the current version of the tape you will probably want to download it first. It is available below in several formats so you can use the one that is most convenient.
