Displays the size of an area in the specified file in FRAMESIZE units and also the number of full sized records that can be completely contained within that area. A full sized record is a record whose size is equal to the value of the MAXRECSIZE modifier.

A file with variable length records can contain records that are smaller than the MAXRECSIZE value and can, therefore, contain a larger number of records in an area. The displayed values do not include any unused portions of the area. The specified file can be either uncrunched or crunched.

Refer to the File Attributes Programming Reference Manual for a description of the AREALENGTH file attribute.
