The RECFM=U would only byte you if you tried to move that kind of data set to a smaller track size. A bigger track size would work, but then you would be wasting space, and DASDs were a lot more expensive then than now.
I think SAS data sets were also unmovable for the first couple of decades.

At the time SAS created RECFM=U datasets with a BLKSIZE that depended on the type of disk. If you just copied the dataset with IEBGENER or some other non SAS utility SAS wouldn't recognize it as a SAS dataset. So all SAS dataset had to be identified and copied using a SAS utility. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
