Hi All,

Is it possible to reduce the size of the PS dataset and copy the same to another dataset.

Could you please help out in this?

Use 3.3 copy and while copying give the new attributes by selecting the allocation option 2.

Depends on what You mean by your question

reduce the size Of the data ... looks like an odd request

reduce the size of the allocated space yes.

when You allocate thru jcl specify the RLSE parameter,
at close time only the used space will be left allocated

after...
from ISPF option 3.4 issue the F for free command and it will release
the allocated but unused space..

Hi E.S,

Please let me know the use of PGM=TRSMAIN.

For this utility, it is mentioned that packing and unpacking of data.

i want to know whether this can be used for compression of dataset.
