Shmuel: I never got to the MSS school myself. The person who “owned” the thing was “Mr DASD” at GUIDE. As I understood it, IBM never for saw the use of TSO people using it causing the 3850 to sort of thrash (don’t quote me as t was 40 or so years ago). It did work well in batch though). As to which device type it was probably a flip of the coin.At the time we were converting volumes with little or no effect on the users. Although we did have a programmer (he should never have been one) have issues with the difference in the space ( long story omitted) between the two. Also, we had issues on most of the catalogs doing the conversion. I can’t remember where but I found a freebie catalog conversion program at a semi government agency that save our back many times doing the conversions between 3330’s and 3350’s.
