Type Definition
Description refer to operations which are performed by the "list" processor, and are one of the three distinct types of verbs in the Pick System.

Access verbs require at minimum a verb and a file.reference, but they additionally support many qualifiers, such as selection and sorting criteria.

In D3, the "list-verbs" command produces an alphabetically organized list of all verbs in a given md, or the current md if one is not explicitly provided. Any verb with an "a" (or "A") in the "A2" column of the "list-verbs" output is considered to be an Access verb.

Access verbs essentially break down into the following categories:

1) columnar-output-producing: sort and list

2) list-producing: select, sselect and nselect

3) statistical: count, sum and stat

4) tape-handling: t-dump, s-dump and t-load

5) file-analysis:  hash-test and istat

6) internal (or "copy") format: list-item and sort-item

7) label-producing: list-label and sort-label

8) file-updating: update, reformat and srefomat
