SUBROUTINE XERSVE (LIBRAR, SUBROU, MESSG, KFLAG, NERR, LEVEL, &
        ICOUNT)
  IMPLICIT NONE
  !***BEGIN PROLOGUE  XERSVE
  !***SUBSIDIARY
  !***PURPOSE  Record that an error has occurred.
  !***LIBRARY   SLATEC (XERROR)
  !***CATEGORY  R3
  !***TYPE      ALL (XERSVE-A)
  !***KEYWORDS  ERROR, XERROR
  !***AUTHOR  Jones, R. E., (SNLA)
  !***DESCRIPTION
  !
  ! *Usage:
  !
  !    INTEGER  KFLAG, NERR, LEVEL, ICOUNT
  !    CHARACTER * (len) LIBRAR, SUBROU, MESSG
  !
  !    CALL XERSVE (LIBRAR, SUBROU, MESSG, KFLAG, NERR, LEVEL, ICOUNT)
  !
  ! *Arguments:
  !
  !    LIBRAR :IN    is the library that the message is from.
  !    SUBROU :IN    is the subroutine that the message is from.
  !    MESSG  :IN    is the message to be saved.
  !    KFLAG  :IN    indicates the action to be performed.
  !                  when KFLAG > 0, the message in MESSG is saved.
  !                  when KFLAG=0 the tables will be dumped and
  !                  cleared.
  !                  when KFLAG < 0, the tables will be dumped and
  !                  not cleared.
  !    NERR   :IN    is the error number.
  !    LEVEL  :IN    is the error severity.
  !    ICOUNT :OUT   the number of times this message has been seen,
  !                  or zero if the table has overflowed and does not
  !                  contain this message specifically.  When KFLAG=0,
  !                  ICOUNT will not be altered.
