Hi, PFILE is used to create a logical file on as/400 and we can create even multiple format logical files by specifying a number of PFs on this Keyword. The purpose of REF in file level is that the logical file is not going to describe about any of the fileds to appear in the file but it's going to reference it from another file. The REF keyword at field level specifies to refer only that field to be referred from the file.
