Hi Siva,

A GDG base cannot be opened. If we need to create any GDG we will create the base and then we will go for creating the generations. A GDG base does not contain any data. For any GDG base the volume shows as ?????? only. Similarly even a tape file can't be seen directly. we will convert tape file to DASD and then we see the data.

And VSAM files can be viewed thru FILEAID.

Hope this helps...

For VSAM files, you can use the 'I' option to view the details. In the keyword section, u can enter any keyword from the list and press enter. Then type EXEC in the next screen showing the command and press enter.
You will get some info abt the VSAM file.

to see the properties of TAPE file use TI option in front of dataset.

Hello and welcome to the forum,

Please note that you have replied to a topic that has been inactive for more than 3 years. . .

If is best to reply to currently active topics.

Also, i believe TI is a site-specific command and will not work everywhere.
