You can use a record-address file to process another file. A record-address file can contain (1) limits records that are used to process a file sequentially within limits, or (2) relative record numbers that are used to process a file by relative record numbers. The record-address file itself must be processed sequentially.
A record-address file is identified by an R in position 18 of the file description specifications. If the record-address file contains relative record numbers, position 35 must contain a T. The name of the file to be processed by the record-address file must be specified on the file description specification. You identify the file using the keyword RAFDATA(file-name).
