FOR$IOS_FLAWEDPENT. The Fortran run-time system detected a flawed Pentium®
processor. Please contact Intel® to upgrade your processor. To allow program
execution to continue when this condition occurs, set the environment variable
FOR_RUN_FLAWED_PENTIUM to true and rerun the program. For more
information, see Intel Pentium Floating-Point Flaw.
256
severe (256): Unformatted I/O to unit open for formatted transfers
FOR$IOS_UNFIO_FMT. Attempted unformatted I/O to a unit where the OPEN
statement (FORM specifier) indicated the file was formatted. Check that the correct
unit (file) was specified. If the FORM specifier was not present in the OPEN statement
and the file contains unformatted data, specify FORM=’UNFORMATTED'in the
OPEN statement. Otherwise, if appropriate, use formatted I/O (such as list-directed or
namelist I/O).
257
severe (257): Formatted I/O to unit open for unformatted transfers
FOR$IOS_FMTIO_UNF. Attempted formatted I/O (such as list-directed or namelist
I/O) to a unit where the OPEN statement indicated the file was unformatted ( FORM
specifier). Check that the correct unit (file) was specified. If the FORM specifier was
not present in the OPEN statement and the file contains formatted data, specify
FORM='FORMATTED' in the OPEN statement. Otherwise, if appropriate, use
unformatted I/O.
264
severe (264): operation requires file to be on disk or tape
FOR$IOS_OPEREQDIS. Attempted to use a BACKSPACE statement on such
devices as a terminal.
265
severe (265): operation requires sequential file organization and access
FOR$IOS_OPEREQSEQ. Attempted to use a BACKSPACE statement on a file
whose organization was not sequential or whose access was not sequential. A
BACKSPACE statement can only be used for sequential files opened for sequential
access.
266¹
error (266): Fortran abort routine called
FOR$IOS_PROABOUSE. The program called the abort routine to terminate itself.
268¹
severe (268): End of record during read
FOR$IOS_ENDRECDUR. An end-of-record condition was encountered during
execution of a nonadvancing I/O READ statement that did not specify the EOR branch
specifier.
297¹
info (297): nn floating invalid traps
FOR$IOS_FLOINVEXC. The total number of floating-point invalid data traps
