+*DECK XGETUA
+      SUBROUTINE XGETUA (IUNITA, N)
+C***BEGIN PROLOGUE  XGETUA
+C***PURPOSE  Return unit number(s) to which error messages are being
+C            sent.
+C***LIBRARY   SLATEC (XERROR)
+C***CATEGORY  R3C
+C***TYPE      ALL (XGETUA-A)
+C***KEYWORDS  ERROR, XERROR
+C***AUTHOR  Jones, R. E., (SNLA)
+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     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.
