Re: File format for an unloaded partitioned data set?
When the files were offloaded were they a seqential dataset or a PDS file? The answer to that question will determine the response.

Re: File format for an unloaded partitioned data set?
2008/5/2 Roger Bowler [EMAIL PROTECTED]: From: Hendrik Boom [EMAIL PROTECTED] I have a few unloaded partitioned data sets dating back to the 70's.

See http://www.hercules-390.org/hercload.html#PDS However, I don't think xmit format existed in the 1970's, XMIT came in with MVS SP1 and TSO/E, in the very early 1980s. so maybe your PDS are unloaded in iehmove format? IEBCOPY unload does not depend on XMIT; XMIT uses IEBCOPY as part of packaging up PDSs into XMIT files. IEBCOPY unload came with SVS, in the early 1970s, and was far easier to use than IEHMOVE for PDSs, so it is quite likely that an unloaded PDS on tape from then would be in IEBCOPY format. The quick way to tell is to look at the record format on tape; if it's fixed with blksize=800, then it's IEHMOVE. If it's VB, then it's IEBCOPY. If this is the case you could install the Turnkey system http://www.bsp-gmbh.com/turnkey/ which is a complete working MVS 3.8 system for Linux and Windows containing everything you need to load and process these files. Indeed. Or of course if you have a modern z/OS system, but no drive on which you can read the old tapes, then you can read the tapes using a suitable Linux utility (dd), transfer the file to z/OS, write it out to a tape, or a sequential file, and run the modern utility to restore. With IEBCOPY, you may have trouble with the VB files. FTP might be a way to maintain the RDWs and such in this case. As for documentation, both formats are de facto documented in the source code for the respective utilities, and to some extent in the PLMs available at bitsavers and other places. Neither format is highly complex, and there is no compression, so writing a program to do it on your own is not extremely complex. And finally, if you just want to get your data, and can physically read the tapes, I'm sure there are many people who would be happy to convert your data for you on a friendly basis.
