TGTALLOC specifies how DFSMSdss is to allocate the target data set.

BLK: by blocks
CYL: by cylinders
TRK: by tracks
SOURCE/SRC: with the same space allocation type as that of the source data set

Note:

If the TGTALLOC keyword is omitted, the target allocation defaults to SOURCE.
If SRC is specified and if the source data set is allocated by track or if TRK is specified, then the final VSAM allocation might be different from the requested one because of VSAM allocation rules.
If BLK is specified for VSAM data sets, TRK is used instead. The final VSAM allocation might be different from the requested one because of VSAM allocation rules.
