fortran iostat error Ray, Ohio

ELSE ... In namelist input, an array name was qualified with a different number of subscripts than its declaration, or a non-array name was qualified. 626 severe (626): Array subscript exceeds allocated area I/O Error Messages (f90) This is a partial list of runtime I/O messages issued by f90 Table A-2 f90 Runtime I/O Messages Error Message 1000format error 1001illegal unit number 1002formatted I/O IOFOCUS was specified in an OPEN or INQUIRE statement for a non-QuickWin application.

A non-CHARACTER item in namelist input was qualified with a substring range. 629 severe (629): Internal file overflow FOR$IOS_F6600. Note: This error can be returned by STAT in a DEALLOCATE statement. 1741 severe (174): SIGSEGV, message-text FOR$IOS_SIGSEGV. An OPEN statement specified STATUS='OLD' for a specified file or a directory path that does not exist. 603 severe (603): Too many open files FOR$IOS_F6417. Check the permissions of the specified file and whether the network device is mapped and available.

A value of -1 if an end-of-file condition occurs. It can be caused by more than 10 levels of nested parentheses or an extremely long format statement. 1001 illegal unit number It is illegal to close logical unit 0. This summary message appears at program completion. 540 severe (540): Array or substring subscript expression out of range FOR$IOS_F6096. close(CHROMOSOME_UNIT, iostat=close_status) if ( close_status /= 0 ) then print *, 'Error: Attempt to close a file that is not open.', & 'unit = ', CHROMOSOME_UNIT stop endif end program The

The code itself works with Composer2011 build 233 although that may be a red-herring! Number Severity Level, Number, and Message Text; Condition Symbol and Explanation 11 severe (1): Not a Fortran-specific error FOR$IOS_NOTFORSPE. ACCESS accepts the values 'SEQUENTIAL' and 'DIRECT'. 573 severe (573): Illegal BLANK value FOR$IOS_F6307. You can optionally perform an INQUIRE statement on the logical unit after the READ statement and before the REWRITE statement.

Check if correct unit number was specified. See your operating system documentation for more information. 1591 severe(159): Program Exception - breakpoint FOR$IOS_PGM_BPT. The specified decimal length D exceeds the specified total field width W in an ES edit descriptor. 635 severe (635): D field exceeds W field in EN edit descriptor FOR$IOS_F6971. An array subscript is outside the dimensioned boundaries of that array.

Otherwise, it will contain a non-zero error code that indicates why the file could not be opened. (Does not exist, no permission, etc.) Optional tags: action: String 'read': Open for reading An invalid segmented record control data word was detected in an unformatted sequential file. Only if Reason is zero, one can start normal processing. An unformatted file did not contain segmented records.

Steve - Intel Developer Support Top mecej4 Tue, 01/08/2013 - 07:14 Here is a small program to reinforce what Steve said. The format associated with an I/O statement that included an I/O list had no field descriptors to use in transferring those values. 61 severe or info(61): Format/variable-type mismatch FOR$IOS_FORVARMIS. If possible, reset your virtual memory size through the Windows Control Panel, or close unneccessary applications and deallocate all allocated arrays that are no longer needed. 673 severe (673): SHAPE and F6302 can indicate an error in spacing or a mismatched format for data of different radices. 569 severe (569): Illegal radix specifier FOR$IOS_F6303.

This is an operating system error. It is your job as a Fortran programmer to choose a unique unit number for each file you open. These messages are listed below. If there is no PAD array, the SOURCE argument to RESHAPE must have enough elements to make an array of the shape specified by SHAPE. 672 severe (672): Out of memory

This is because commas are disabled as input field delimiters if left tabbing leaves the record positioned in a previous buffer. Examples In the following code, the DO-loop keeps reading in three integer values into variables a, b and c. This trap is reported if the rounded result of an IEEE operation is not exact. 1441 severe (144): Reserved operand FOR$IOS_ROPRAND. The file was probably either created with RECORDTYPE='FIXED' or 'VARIABLE' in effect, or was created by a program written in a language other than Fortran or Fortran 90. 36 severe (36):

FOR$IOS_FILNOTFOU) THEN WRITE (6,*) 'File: ', FILNM, ' does not exist ' ELSE IF (IERR .EQ. It could be so large to be counted accurately. If appropriate, use an OPEN statement to explicitly open the file (connect the file to the unit number). 17 severe (17): Syntax error in NAMELIST input FOR$IOS_SYNERRNAM. You ran out of memory for them; that is, your program is too big. 1014 unit not connected The logical unit was not open. 1015 read unexpected character Certain format conversions

See Data Representation for ranges for INTEGER types. 1661 severe(166): Program Exception - privileged instruction FOR$IOS_PGM_PRIVINST. One or more BN, BZ, S, SS, SP, T, TL, TR, /, $, :, or apostrophe (') edit descriptors had repeat counts associated with them. 641 severe (641): Integer expected preceding An OPEN statement specified a connection between a unit and a filename that was already in effect. The Intel Fortran RTL I/O system detected an error condition during execution of a WRITE statement. 39 severe (39): Error during read FOR$IOS_ERRDURREA.

The only documentation I've found says that this is a file not found error, but the file already been opened on a given unit without error. Either an illegal character appeared as part of an integer, or a numeric character larger than the radix was used in an alternate radix specifier. 546 severe (546): REAL indefinite (uninitialized During a formatted output operation, the value of a particular number could not be output in the specified field length without loss of significant digits. An OPEN statement in which IOFOCUS was TRUE, either explicitly or by default, failed because the new window could not receive focus.

The program tried to read more data from an unformatted file than the current record contained. Communicate between the EXE and DLL using file-name, not file-unit-number (if some of the code is in C/C++, you would not be using I/O unit numbers, in all likelihood). Note: This error can be returned by STAT in an ALLOCATE statement. 1521 severe (152): Unresolved contention for DEC Fortran RTL global resource FOR$IOS_RESACQFAI. A REC= option was included in a statement that transferred data to a file that was opened with the ACCESS='SEQUENTIAL' option. 555 severe (555): Unformatted I/O not consistent with OPEN options

An illegal value was used with the BLANK option. A POINTER used as an argument to the ASSOCIATED function must be defined; that is, assigned to a target, allocated, or nullified. 659 severe (659): Reference to uninitialized POINTER FOR$IOS_F6704. The error message may indicate a CLOSE error when the fault is actually coming from WRITE.
