When allocating space for the output data set SYSUT2, you must
estimate the required size information:
- For the PACK or SPACK option a data set compressed by AMATERSE
is expected to be about half the size of the original. Allocate more
than expected and use the RLSE (partial release parameter) function
of the SPACE value to release the unused portion back to the system.
- For the UNPACK option: If the data set contains random data, allocate
three to five times the size of the compressed data set. If the data
set contains Listing, Document, or Messages type data, allocate five
to ten times the size of the compressed data set.
If there is not enough allocated space, the program issues ABEND
X'B37':
Not Enough Space Allocated for the Output Data Set
