Traditional File Description Specification Statement

The general layout for the file description specification is as follows:
  • the file description specification type (F) is entered in position 6
  • the non-commentary part of the specification extends from position 7 to position 80
    • the fixed-format entries extend from positions 7 to 42. For files defined with the LIKEFILE keyword, the entries from position 17 to position 43 must be blank. The values for those fixed-form entries are taken from the parent file specified by the LIKEFILE keyword.
    • the keyword entries extend from positions 44 to 80
  • the comments section of the specification extends from position 81 to position 100
