Selecting Record Formats for Non-VSAM Data Sets

This topic discusses record formats of non-VSAM data sets and device type considerations. Records are stored in one of four formats:

  • Fixed length (RECFM=F)
  • Variable length (RECFM=V)
  • ASCII variable length (RECFM=D)
  • Undefined length (RECFM=U)
