Fortran 90, 95, 2003, and 2008 standard language errors
Fortran 90 standard language errors
A Fortran 90 language error results from the use of XL Fortran extensions to the Fortran 90 language that cannot be detected at compile time. A Fortran 90 language error is considered a severe error when the LANGLVL run-time option has been specified with the value 90STD and the ERR_RECOVERY run-time option has either not been set or is set to NO. If both LANGLVL=90STD and ERR_RECOVERY=YES have been specified, the error is considered a recoverable error. If LANGLVL= EXTENDED is specified, the error condition is not considered an error.
Fortran 95 standard language errors
A Fortran 95 language error results from the use of XL Fortran extensions to the Fortran 95 language that cannot be detected at compile time. A Fortran 95 language error is considered a severe error when the LANGLVL run-time option has been specified with the value 95STD and the ERR_RECOVERY run-time option has either not been set or is set to NO. If both LANGLVL=95STD and ERR_RECOVERY=YES have been specified, the error is considered a recoverable error. If LANGLVL=EXTENDED is specified, the error condition is not considered an error.
Fortran 2003 standard language errors
A Fortran 2003 standard language error results from the use of XL Fortran extensions to the Fortran 2003 language standard that cannot be detected at compile time. A Fortran 2003 language error is considered a severe error when the LANGLVL run-time option has been specified with the value 2003STD and the ERR_RECOVERY run-time option has either not been set or is set to NO. If both LANGLVL=2003STD and ERR_RECOVERY=YES have been specified, the error is considered a recoverable error. If LANGLVL=EXTENDED is specified, the error condition is not considered an error.
Fortran 2008 standard language errors
A Fortran 2008 standard language error results from the use of XL Fortran extensions to the Fortran 2008 language standard that cannot be detected at compile time. A Fortran 2008 language error is considered a severe error when the LANGLVL run-time option has been specified with the value 2008STD and the ERR_RECOVERY run-time option has either not been set or is set to NO. If both LANGLVL=2008STD and ERR_RECOVERY=YES have been specified, the error is considered a recoverable error. If LANGLVL=EXTENDED is specified, the error condition is not considered an error.
| IOSTAT Value | Error Description |
|---|---|
| 53 | Mismatched edit descriptor and item type in formatted I/O. |
| 58 | Format specification error. |
| 140 | Unit is not connected when the I/O statement is attempted. Only for READ, WRITE, PRINT, REWIND, and ENDFILE. |
| 141 | Two ENDFILE statements without an intervening REWIND or BACKSPACE on the unit. |
| 151 | The FILE= specifier is missing and the STATUS= specifier does not have a value of 'SCRATCH' on an OPEN statement. |
| 187 | NAMELIST comments are not allowed by the Fortran 90 standard. |
| 199 | STREAM is not a valid value for the ACCESS= specifier on an OPEN statement in Fortran 90 or Fortran 95. |
