RE: COBOL WRITE after OPEN EXTEND results in CLEAR-AFTER-WRITE

To piggyback on Ricks post, here's the text from the WG4
committee for Cobol which has been there for quite some
time.  I have reformatted it slightly....

----------------------------------------------------------------------------

Reference number of working document: ISO/IEC/JTC 1/SC 22/WG 4N 0147
Date: 2001-12-04
Reference number of document:
ISO/IEC IS 1989:2001

14.8.47.3 General rules ALL FILES

1) The write file connector is the file connector associated with the
write file. If the access mode of the write file is sequential, the open
mode of the write file connector shall be extend or output. Otherwise, the
open mode of the write file connector shall be I-O or output. If the open
mode is not as described, the execution of the WRITE statement is
unsuccessful
and the I-O status for the write file connector is set to '48'.

2) The logical record released by the successful execution of the WRITE
statement
is no longer available in the record area unless the file-name associated
with
record-name-1 is specified in a SAME RECORD AREA clause.  The logical record

is also available as a record of other files referenced in the same SAME
RECORD
AREA clause as the associated output file, as well as the file associated
with
record-name-1.

3) The result of the execution of a WRITE statement specifying record-name-1
and
the FROM phrase is equivalent to the execution of the following statements
in
the order specified:
        a) The statement:
                MOVE identifier-1 TO record-name-1
        or
                MOVE literal-1 TO record-name-1
according to the rules specified for the MOVE statement.
