Closes the default output destination or the
output stream you name with the STREAM keyword in a prior OUTPUT TO statement.
Syntax
OUTPUT [ STREAM stream | STREAM-HANDLE handle ] CLOSE
|
- STREAM stream
- Specifies the name of a stream. If you do not name a stream,
the AVM uses the unnamed stream. See the DEFINE STREAM statement reference entry and the chapter on alternate I/O sources
in OpenEdge Development: Programming Interfaces for
more information on streams.
- STREAM-HANDLE handle
- Specifies the handle to a stream. If handle it
is not a valid handle to a stream, the AVM generates a run-time
error. Note that stream handles are not valid for the unnamed streams.
See the chapter on alternate I/O sources in OpenEdge Development:
Programming Interfaces for more information on streams and
stream handles.
Example
This
procedure sends Customer data to a file by using the OUTPUT TO statement.
All statements that normally send output to the terminal send output to
the file named cust.dat. After all Customer
data is written to the file, the OUTPUT CLOSE statement resets the
output destination, usually the terminal. The final DISPLAY statement
displays "Finished" on the terminal.
r-out.p
OUTPUT TO cust.dat.
FOR EACH Customer NO-LOCK:
DISPLAY Customer.CustNum Customer.Name Customer.Address Customer.Address2
Customer.City Customer.State Customer.Country SKIP(2)
WITH 1 COLUMN SIDE-LABELS.
END.
OUTPUT CLOSE.
DISPLAY "Finished".

Notes
- The
default output destination is the destination that was active when
the procedure began. The output destination is usually the terminal unless
the current procedure was called by another procedure while a different
destination was active.
- A form feed (new page) is automatically output when a PAGED output
stream is closed.
- If the output destination is the Windows clipboard, this statement writes
all buffered output data to the clipboard in CF-TEXT format and clears
the buffer.
- For more information on directing output, see OpenEdge Development:
Programming Interfaces.
