RETURN statement

The RETURN statement transfers records from the final phase of a sorting or merging operation to an OUTPUT PROCEDURE.

The RETURN statement can be used only within the range of an OUTPUT PROCEDURE associated with a SORT or MERGE statement.

Within an OUTPUT PROCEDURE, at least one RETURN statement must be specified.

When the RETURN statement is executed, the next record from file-name-1 is made available for processing by the OUTPUT PROCEDURE.

file-name-1
Must be described in a DATA DIVISION SD entry.

If more than one record description is associated with file-name-1, those records automatically share the same storage; that is, the area is implicitly redefined. After RETURN statement execution, only the contents of the current record are available. If any data items lie beyond the length of the current record, their contents are undefined.

INTO phrase
When there is only one record description associated with file-name-1 or all the records and the data item referenced by identifier-1 describe an elementary alphanumeric item or an alphanumeric group item, the result of the execution of a RETURN statement with the INTO phrase is equivalent to the application of the following rules in the order specified:
  • The execution of the same 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 for 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 RETURN statement was unsuccessful. Any subscripting or reference modification associated with identifier-1 is evaluated after the record has been read 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.

When there are multiple record descriptions associated with file-name-1 and they do not all describe an alphanumeric group item or elementary alphanumeric item, the following rules apply:

  1. If the file referenced by file-name-1 contains variable-length records, a group move takes place.
  2. If the file referenced by file-name-1 contains fixed-length records, a move takes place according to the rules for a MOVE statement using, as a sending field description, the record that specifies the largest number of character positions. If more than one such record exists, the sending field record selected will be the one among those records that appears first under the description of file-name-1.

identifier-1 must be a valid receiving field for the selected sending record description entry in accordance with the rules of the MOVE statement.

The record areas associated with file-name-1 and identifier-1 must not be the same storage area.

AT END phrases

The imperative-statement specified on the AT END phrase executes after all records have been returned from file-name-1. No more RETURN statements can be executed as part of the current output procedure.

If an at-end condition does not occur during the execution of a RETURN statement, then after the record is made available and after executing any implicit move resulting from the presence of an INTO phrase, control is transferred to the imperative statement specified by the NOT AT END phrase. If an at-end condition does occur, control is transferred to the end of the RETURN statement.

END-RETURN phrase

This explicit scope terminator serves to delimit the scope of the RETURN statement. END-RETURN permits a conditional RETURN statement to be nested in another conditional statement. END-RETURN can also be used with an imperative RETURN statement.
