VMS Help FORTRAN, Format Specifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  A FORMAT statement specifies the format in which data is to be
  transferred and the conversion (editing) required to achieve that
  format.  FORMAT statements are nonexecutable statements used with
  formatted I/O statements, ASSIGN statements, and with ENCODE and
  DECODE statements.

  Fields defined by a FORMAT statement can contain variable format
  expressions.  A variable format expression is an integer variable
  or expression enclosed in angle brackets that takes the place of an
  integer constant.  The value of the variable or variables can
  change during program execution.
