Notes:
The SIZE = U parameter cannot be used with TPF data sets. For TPF data sets only SIZE = L, S, or 4 will be accepted.
The SIZE = U parameter is used for non-TPF data sets; such as OS data sets. When SIZE = U is specified the data set is divided into 4K-byte allocations. If the data set was not defined by the user to 4K-byte allocations, any additional records at the end of the tracks will not be addressable.
