gtpm1m16TPF V4R1 Migration Guide: 3.1 to 4.1

Reformatting Online Modules

Because all E-type programs are 4 KB in size and will be 4 KB on DASD, you may need to reformat your online modules as well as your general files.

The TPF DASD formatter now supports 4-digit DASD numbers. In the TPF 3.1 system, the volume serial number (VSN) naming scheme was LXXXZZZZ where:

L
Was the device type letter

XXX
Was the 3-digit DASD number

ZZZZ
Was the subsystem name.

In the TPF 4.1 system, the naming scheme is LXXXX.ZZZZ.
