A little math. x'CD13' = 52499. Since this is relative to zero, make that 52500. Track 52500 is cylinder 3500, a coincidentally very round number. Could it be that you have 3500 cylinders on the first volume of a multi-volume file?
If I recall my BSAM days, you can't simply point to data on the second or subsequent volume of a multi-volume data set. I always used another DCB for each volume. I don't believe BSAM prevents you from processing the data sequentially across multiple volumes, which might explain the phenomenon you are seeing. >The problem I am having is that I cannot POINT to a track beyond 00CD1308 >and successfully read that track (I get a 42 condition in the ECB).
