CCL (Common Command Language)
A standard text retrieval query
language proposed by the International Organization for Standardization
(ISO).
The standard represents an attempt to standardize
commands in online databases, e.g., commands like "find", "stop" and "truncation".
A simple command like "stop" may in different search systems be expressed by,
for example, "logout", "logoff", "quit", "end", "stop", "off", "bye", "out"
etc. If many different database hosts are used by the same searchers is this an essential problem
causing confusion.
Garman (1995, p. 8) finds that "a common command language or search interface is definitely an antique notion in today's fast-paced online world".
