25⟩ What is difference between rename and prefix?
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.
