One of them took on tape as a general issue. They wrote a (yellow/orange?- before the orange books actually meant something special) the book (Forgot the number) he did a study on how much buffering tape would decrease run time (he actually took production jobs (with the owners permission of course) and added dcb=bufno= on various dd cards and of course it dramatically decreased run time. 6 Months after publication, IBM offered SAMe at $60 a month. I think we were ESP and it did help but it also uncovered bad code in 8 or so IBM modules. I think I had 4 apars and another sysprog had 4, IBM took on some. All in all not too bad. This was during the switchover time frame from STC back to IBM. The STC CE’s were jerks about getting kicked out and they dragged their feet getting out. When the last one left we all stood up and clapped. Our management noticed the the STC people were being jerks and told the customer manager for STC never to darken our door again.
