Hi Mattias,
unfortunately calculating wouldn't be a problem (we use a very well
defined
SPACE parameter set, depending on the amount of records rather than TRK or
CYL). It is finding the actual parameters of an *existing* dataset that is
the issue. To be more clear - I have a lot of datasets, I need to
manipulate
them, but I have no way of knowing what their size is. I am now trying to
find that way :)
Since posting the original message I've gone through DFSMS manual, IDCAMS
etc. Yet no cigar so far...
Thanks for your input though :)
