GLOBAL ROUTINE EDT$$TI_FLUSHJOUFI (		! Flush journal file
    RECORD_TYPE					! text or control C
    ) : NOVALUE =

!++
! FUNCTIONAL DESCRIPTION:
!
!	This routine writes either a text record or a control C record.
!	A text record is taken from the journal buffer.  A control C record
!	consists of the count of the number of times we tested for control C
!	and didn't find it.  Upon writing either record the control c counter
!	is cleared; thus it records the number of tests since the last journal
!	record.
!
! FORMAL PARAMETERS:
!
!	RECORD_TYPE	ASCII 'T' for a text record, ASCII 'C' for a control C record.
!
! IMPLICIT INPUTS:
!
!	TIN_OBUF
!	TIN_OBUFPOS
!	CC_CNT1
!	JOU_VALID
!
! IMPLICIT OUTPUTS:
!
!	TIN_OBUFPOS
!	JOU_VALID
!
! ROUTINE VALUE:
!
!	NONE
!
! SIDE EFFECTS:
!
!	NONE
