*+
*  Name:
*     SLN_PUTRNGI

*  Purpose:
*     Write selector consisting of range pairs

*  Language:
*     Starlink Fortran

*  Invocation:
*     CALL SLN_PUTRNGI( SID, QNAM, NRNG, START, STOP, STATUS )

*  Description:
*     {routine_description}

*  Arguments:
*     SID = INTEGER (given)
*        ADI identifier of selection record
*     QNAM = CHARACTER*(*) (given)
*        Name of selection quantity
*     NRNG = INTEGER (given)
*        Number of ranges
*     START[] = INTEGER (given)
*        Array of range lower bounds
*     STOP[] = INTEGER (given)
*        Array of range upper bounds
*     STATUS = INTEGER (given and returned)
*        The global status.
