# ACCESS (AQL)

The ACCESS Query Language (AQL) is a D3 facility used to
retrieve and output data and consists of the List preprocessor, the
Select processor, and the Output processor. AQL is a system-level
information retrieval language that allows users to query their database
without writing complex programs.

AQL uses TCL commands and displays the results either
on terminals or printers. AQL operates on specified files and items
based on various optional criteria, specifications, modifiers, limiters,
and options.
