Syntax Rules

  1. MF F and FIXED are synonyms.
  2. MF V and VARIABLE are synonyms.

General Rules for All Formats (All Files)

  1. Specifying RECORDING MODE IS F causes all the records in the file to be the same length.

General Rules for Format 1 (Record Sequential Files)

  1. MF The "U" option is documentary only.

General Rules for Formats 1 and 3 (Record Sequential,Relative and Indexed Files)

  1. When RECORDING MODE IS V is specified, the records in the file can be either fixed or variable in length. Each data record includes a record length field. These fields are not part of the record description.
MF 

General Rules for Format 2 (Line SequentialFiles)

  1. MF Line sequential files are neither truly fixed nor truly variable format files: the presence or absence of any RECORDING MODE, RECORD CONTAINS or RECORD VARYING IN SIZE clause does not, therefore, impact their performance.
