INQUIRE: RECL Specifier

The RECL specifier asks the maximum record length for a file. It takes the following form:

RECL = rcl

rcl

Is a scalar integer variable that is assigned a value as follows:

  • If the file or unit is connected, the value assigned is the maximum record length allowed.

  • If the file does not exist, or it is not connected, the value assigned is zero.

    Fortran 2018 standardizes the value assigned to be -1 when the file does not exist, or it is not connected. To get the Fortran 2018 behavior, specify compiler option assume -noold_inquire_recl.

  • If the file is connected for stream access, the value is undefined. Fortran 2018 standardizes this value to be -2. To get the Fortran 2018 behavior, specify compiler option assume -noold_inquire_recl.

The assigned value is expressed in 4-byte units if the file is currently (or was previously) connected for unformatted data transfer and the assume byterecl compiler option is not in effect; otherwise, the value is expressed in bytes.
