CRC-VALUE attribute

The cyclic redundancy check (CRC) value for either an r-code file, or a database table corresponding to a buffer object.

Data type: INTEGER

Access: Readable

Applies to: Buffer object handle, RCODE-INFO system handle

When applied to the RCODE-INFO system handle, the r-code CRC is calculated using the filename and contents of the r-code file specified by the RCODE-INFO:FILE-NAME attribute.

When applied to the Buffer object handle, the database CRC is calculated using the metaschema _CRC field value from the _File record for the database record corresponding to the buffer object's table (which can be a standard or temp-table).

The CRC for a temp-table is calculated differently than for a standard table. Some differences include:
