Answer / muttaiah
1) The dataset should be of same type meaning if you are
concatenating a PDS then other ds should be pds only & ps-
Ps)
2) They should have same format and LRECL
3) If the dataset's have diff blocksize then the dataset
with Largest block size should be coded first
4) All the datasets should reside on the same unit(device).
however the volume serial number can differ
5) we can concatenate 16 PDS & 255 PS files
