C***DESCRIPTION

C

C     Abstract

C        XGETUA may be called to determine the unit number or numbers

C        to which error messages are being sent.

C        These unit numbers may have been set by a call to XSETUN,

C        or a call to XSETUA, or may be a default value.

C

C     Description of Parameters

C      --Output--

C        IUNIT - an array of one to five unit numbers, depending

C                on the value of N.  A value of zero refers to the

C                default unit, as defined by the I1MACH machine

C                constant routine.  Only IUNIT(1),...,IUNIT(N) are

C                defined by XGETUA.  The values of IUNIT(N+1),...,

C                IUNIT(5) are not defined (for N .LT. 5) or altered

C                in any way by XGETUA.

C        N     - the number of units to which copies of the

C                error messages are being sent.  N will be in the

C                range from 1 to 5.
