     +   ICOUNT)
C***BEGIN PROLOGUE  XERSVE
C***SUBSIDIARY
C***PURPOSE  Record that an error has occurred.
C***LIBRARY   SLATEC (XERROR)

C***DESCRIPTION
C
C *Usage:
C
C        INTEGER  KFLAG, NERR, LEVEL, ICOUNT
C        CHARACTER * (len) LIBRAR, SUBROU, MESSG
C
C        CALL XERSVE (LIBRAR, SUBROU, MESSG, KFLAG, NERR, LEVEL, ICOUNT)
C
C *Arguments:
C
C        LIBRAR :IN    is the library that the message is from.
C        SUBROU :IN    is the subroutine that the message is from.
C        MESSG  :IN    is the message to be saved.
C        KFLAG  :IN    indicates the action to be performed.
C                      when KFLAG > 0, the message in MESSG is saved.
C                      when KFLAG=0 the tables will be dumped and
C                      cleared.
C                      when KFLAG < 0, the tables will be dumped and
C                      not cleared.
C        NERR   :IN    is the error number.
C        LEVEL  :IN    is the error severity.
C        ICOUNT :OUT   the number of times this message has been seen,
C                      or zero if the table has overflowed and does not
C                      contain this message specifically.  When KFLAG=0,
C                      ICOUNT will not be altered.
