TGTALLOC specifies, during a logical data set restore function, how DFSMSdss will allocate the target data set.

BLK: Specifies to allocate by blocks.
CYL: Specifies to allocate by cylinders.
TRK: Specifies to allocate by tracks.
SOURCE/SRC: Specifies to allocate 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 can be different from the requested one because of VSAM allocation rules.
