Usage of CQLThe CQL program must be run from the command line in a DOS prompt or, on Unix or MacOS systems, from a shell. The program takes a single command-line argument, the name of a cql file, which must have a ".cql" extension.
C:\> cd cql5 C:\cql5> cql idealmirrormate.cql
Sample CQL files are available here. The ".cql" extension is added by default if missing in the command line invocation.
The meaning of a CQL file is determined by the CQL syntax
