The RENAME keyword allows you to rename record formats in an externally described file. The external name of the record format that is to be renamed is entered as the Ext_format parameter. The Int_format parameter is the name of the record as it is used in the program. The external name is replaced by this name in the program.
To rename all fields by adding a prefix, use the PREFIX keyword.
Remember that for a qualified file, the unqualified form of the record format name is used for both parameters of the RENAME keyword.
