6.1.8.9.3 INTO/FROM Identifier Phrase
This phrase is valid for READ, RETURN, RELEASE, REWRITE, and WRITE statements. The identifier specified must be the name of an entry in the Working-Storage Section or the Linkage Section, or of a record description for another previously opened file. Record-name/file-name and identifier must not refer to the same storage area.

The result of the execution of a READ or RETURN statement with the INTO phrase is equivalent to the application of the following rules in the order specified:
- The execution of the same READ or RETURN statement without the
INTO phrase.
- The current record is moved from the record area to the area
specified by identifier-1 according to the rules for the MOVE
statement without the CORRESPONDING phrase. The size of the
current record is determined by rules specified in the RECORD
clause. If the file description entry contains a RECORD IS
VARYING clause, the implied move is a group move. The implied
MOVE statement does not occur if the execution of the READ or
RETURN statement was unsuccessful. Any subscripting or
reference-modification associated with identifier-1 is evaluated
after the record has been read or returned and immediately before
it is moved to the data item. The record is available in both the
record area and the data item referenced by identifier-1.
The result of the execution of a RELEASE, REWRITE, or WRITE statement with the FROM phrase is equivalent to the execution of the following statements in the order specified:
MOVE identifier-1 TO record-name-1
The same RELEASE, REWRITE, or WRITE statement without the FROM phrase.
After the execution of the RELEASE, REWRITE or WRITE statement is complete, the information in the area referenced by identifier-1 is available, even though the information in the area referenced by record-name-1 is not available, except specified by the SAME RECORD AREA clause.
