If you browse the same storage locations or control blocks frequently, you might want to set up a file that names those storage locations so that you can use a name in the BROWSE command.

To enable the BROWSE command to use a named reference to storage, you must allocate a sequential file to the ddname ISRDDN. Each line in that file is either a comment or a named storage location. Comments start with a semi-colon (;).

Location definitions have a name as the first word, followed by a TSO TEST style locator string. Anything after the locator string is ignored. The TSO TEST locator string can use another defined name as a starting point. If the locator string cannot be resolved because of syntax or other errors, the line is ignored.

For example, if you allocate a sequential file like the one shown in Figure 1 to ddname ISRDDN, you could then browse your User Profile Table, which stores your TSO PROFILE settings, by typing B UPT on the command line.
