There is more than one way to mount and access PDS and PDSE members. For example, you can display the existing PDS member smith.source(bigblue) by entering either of these command sequences.

$ mkdir /mnt
# mount hostname:"smith.source,text" /mnt
$ cat /mnt/bigblue

Or

$ mkdir /mnt
# mount hostname:"smith,text" /mnt
$ cat /mnt/source/bigblue
