Explanation:

The user-defined list variable VAR contains three elements.

The specification inf=*par(alloc=*yes) causes all file attributes of the selected files to be output that are relevant for memory allocation. The file attributes F-NAME, CAT-ID, USER-ID,....,EXT form the structure elements. The element EXT is again a list consisting of the elements VOL, DEV and NUM-OF-EXT.

If the information about an object can be organized in a hierarchical structure as for element EXT, a complex S variable is defined as an element of the superordinate structure. The subordinate S variable can be a simple S variable (as for VOL, DEV, NUM-OF-EXT), a structure of a list of simple S variables and/or structures.

The names of the list elements (e.g. F-NAME, F-SIZE) are command-specific and predefined for each SHOW command. They are appended to the names of the S variables as declared by the user. For each further hierarchical level of information, another name is appended, separated by a period.
