QRG2022

The length-of-key-field or the length-of-record-address entry (positions 29-30) of a file-description specification is not blank for a program-described file that is not indexed (I for the file-organization entry (position 32)) or it is not a record-address file (R for the file-designation entry (position 16)). The entry defaults to blanks.

If the file is indexed, specify I for the file-organization option (position 32); if it is a record-address file, specify R for file-designation option (position 16); otherwise omit the length-of-key-field or record-address-field option (positions 29-30). Compile again.
