REAN is a CAOS command for Catalogue access.

Usage

Syntax: REAN tagname (string)

Returns, as an integer, the number of fields in tagname, if it exists. The index of the last field in the tag will be 1 less than the return, as they are numbered from 0. If tagname is not present in the catalogue, REAN fails with a Catalogue error.
