'whoowns' or 'whosgot' are site specific and probably invoke isrddn.
'left side of the DSN'? If you are going to give info, at least provide the complete story. Apparently you mean that you can enter the rexx/clist command 'whoowns/whosgot' as a line command in the ispf 3.4 screen.
PF1 twice when 'dataset in use' is mvs.
nice thing about <TSO ISRDDN ENQ dsn> is that you can enter this on any command line, without invoking the 3.4 screen.
