The BRECLEN function returns the length of a binary record description for a given record layout. Binary record descriptions are typically COBOL and are used for IMS segments, VSAM and flat file records. The length returned represents the maximum length of the description which may be different from the record length of an individual record if the record is variable length in which case the record may contain an OCCURS clause to facilitate processing.

Parameters and Descriptions
| Parameter | Description |

| <record_description_alias> | <variable> | 'literal' | Must resolve at runtime to the alias of a record DESCRIPTION alias. |
Example
Control the processing of changed IMS Segment data by first determining the maximum length of a binary record description.
