gtpm1m2g | TPF V4R1 Migration Guide: 3.1 to 4.1 |
In the TPF 4.1 system, all E-type programs are 4 KB in size and reside in 4 KB file records. As a result, the amount of DASD you need to allocate for programs has grown, and could take up as much as three times the amount of space.
If DASD space is a consideration, you can conserve DASD by packing programs, resegmenting them, or combining them so that more than one program fits into a 4 KB record.
