SUBROUTINE WCI1_CHKPNM( NAME, STATUS )
*+
*  Name:
*     WCI1_CHKPNM

*  Purpose:
*     Check a WCI map projection name

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL WCI1_CHKPNM( NAME, STATUS )

*  Description:
*     Tests the candidate map projection name NAME against the allowed
*     names. Only the first 3 characters of the name are considered. If the
*     name is invalid then an error is reported. This is an internal routine 
*     for use within WCI.

*  Arguments:
*     NAME = CHARACTER*(*) (given)
*        Name of the map projection
*     STATUS = INTEGER (given and returned)
*        The global status.

*  Examples:
*     {routine_example_text}
*        {routine_example_description}
