gtpm1m38 | TPF V4R1 Migration Guide: 3.1 to 4.1 |
There are two new ZDSMG commands in the TPF 4.1 system. You can use the ZDSMG DEFINE command to assign a data definition name to an input device. You can use this data definition name to access the input device if you use the Data Set utility. You can use the ZDSMG RELEASE command to remove a data definition name from the TPF system. Once you release a data definition name, it is not redefined when you perform an initial program load (IPL) of the system.
Because the TPF 4.1 system now supports a number of new input devices, the ZDSMG DISPLAY command was changed to display information about tape, virtual reader, and user-defined input devices, as well as general data set (GDS) input devices.
See TPF Operations for a complete description of the ZDSMG command.
