The table below lists the errors processed by the Intel Fortran run-time library (RTL). For each error, the table provides the error number, the severity code, error message text, condition symbol name, and a detailed description of the errors.
To define the condition symbol values (PARAMETER statements) in your program, include the following file:
/opt/intel/fc/9.0/include/for_iosdef.f
As described in the table, the severity of the message determines which of the following occurs:: program execution continues with info and warning, the results might be incorrect with error, and program execution stops (unless a recovery method is specified) with severe. In the last case, to prevent program termination, you must include either an appropriate I/O error-handling specifier and recompile or, for certain errors, change the default action of a signal before you run the program again.
The first column lists error numbers returned to IOSTAT variables when an I/O error is detected.
The first line of the second column provides the message as it is displayed (following forrtl:), including the severity level, message number, and the message text. The following lines of the second column contain the status condition symbol (such as FOR$IOS_INCRECTYP) and an explanation of the message.
Number | Severity Level, Number, and Message Text; Condition Symbol and Explanation |
---|---|
None 1 | info: Fortran error message number is nnn
The Intel Fortran message catalog file was not found on this system. This error has no condition symbol. |
None 1 | warning:
Could not open message catalog: ifcore_msg.cat
The Intel Fortran message catalog file was not found on this system. This error has no condition symbol. |
None 1 | info:

The Intel Fortran message catalog file was not found. This error has no condition symbol. |
None 1 | Insufficient memory to open Fortran RTL catalog:
message 41
The Intel Fortran message catalog file could not be opened because of insufficient virtual memory. To overcome this problem, increase the per-process data limit by using the limit (C shell) or ulimit (Bourne* and Korn and bash shells) commands before running the program again. For more information, see error 41. This error has no condition symbol. |
1 1 | severe (1): Not a Fortran-specific error
FOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not a Intel Fortran-specific error and was not reportable through any other Intel Fortran run-time messages.

FOR$IOS_RECNUMOUT. A direct access READ, WRITE, or FIND statement specified a record number outside the range specified when the file was opened. |
26 | severe (26): OPEN or DEFINE FILE required
FOR$IOS_OPEDEFREQ. A direct access READ, WRITE, or FIND statement was attempted for a file when no prior DEFINE FILE or OPEN statement with ACCESS= ' DIRECT ' was performed for that file. |
27 | severe (27): Too many records in I/O statement
FOR$IOS_TOOMANREC. An attempt was made to do one of the following:
|
28 | severe (28): CLOSE error

30 | severe (30): Open failure
FOR$IOS_OPEFAI. An error was detected by the Intel Fortran RTL I/O system while attempting to open a file in an OPEN, INQUIRE, or other I/O statement. This message is issued when the error condition is not one of the more common conditions for which specific error messages are provided. It can occur when an OPEN operation was attempted for one of the following:
|
31 | severe (31): Mixed file access modes
FOR$IOS_MIXFILACC. An attempt was made to use any of the following combinations:
|
32 | severe (32): Invalid logical unit number

41 | severe (41): Insufficient virtual memory
FOR$IOS_INSVIRMEM. The Intel Fortran RTL attempted to exceed its available virtual memory while dynamically allocating space. To overcome this problem, increase the per-process data limit by using the limit (C shell) or ulimit (Bourne* and Korn and bash shell) commands before you run this program again. To determine whether the maximum per-process data size is already allocated, check the value of the maxdsiz parameter in the sysconfigtab or system configuration file. If necessary, increase its value. Changes to do not take effect until the system has been rebooted (you do not need to rebuild the kernel if you modify sysconfigtab). Before you try to run this program again, wait until the new system resources take effect. |
42 | severe (42): No such device
FOR$IOS_NO_SUCDEV. A pathname included an invalid or unknown device name when an OPEN operation was attempted. |
43 | severe (43): File name specification error

FOR$IOS_INCRECTYP. The RECORDTYPE value in an OPEN statement did not match the record type attribute of the existing file that was opened. |
45 | severe (45): Keyword value error in OPEN statement
FOR$IOS_KEYVALERR. An improper value was specified for an OPEN or CLOSE statement specifier requiring a value. |
46 | severe (46): Inconsistent OPEN/CLOSE parameters
FOR$IOS_INCOPECLO. Specifications in an OPEN or CLOSE statement were inconsistent. Some invalid combinations follow:
|
47 | severe (47): Write to READONLY file
FOR$IOS_WRIREAFIL. A write operation was attempted to a file that was declared ACTION= ' READ ' or READONLY in the OPEN statement that is currently in effect. |
48 | severe (48): Invalid argument to Fortran Run-Time
Library
FOR$IOS_INVARGFOR. The compiler passed an invalid or improperly coded argument to the Intel Fortran RTL. This can occur if the compiler is newer than the RTL in use. |
51 | severe (51): Inconsistent file organization
FOR$IOS_INCFILORG. The file organization specified in an OPEN statement did not match the organization of the existing file. |
53 | severe (53): No current record
FOR$IOS_NO_CURREC. Attempted to execute a REWRITE statement to rewrite a record when the current record was undefined. To define the current record, execute a successful READ statement. You can optionally perform an INQUIRE statement on the logical unit after the READ statement and before the REWRITE statement. No other operations on the logical unit may be performed between the READ and REWRITE statements. |
55 | severe (55): DELETE error
FOR$IOS_DELERR. An error condition was detected by the Intel Fortran RTL I/O system during execution of a DELETE statement. |

62 | severe (62): Syntax error in format
FOR$IOS_SYNERRFOR. A syntax error was encountered while the RTL was processing a format stored in an array or character variable. |
63 | error or info 3
(63): Output conversion error
FOR$IOS_OUTCONERR 2. 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. When this situation is encountered, the overflowed field is filled with asterisks to indicate the error in the output record. If no ERR address has been defined for this error, the program continues after the error message is displayed. |
64 | severe (64): Input conversion error
FOR$IOS_INPCONERR 2. During a formatted input operation, an invalid character was detected in an input field, or the input value overflowed the range representable in the input variable. The value of the variable was set to zero. |
65 | error (65): Floating invalid
FOR$IOS_FLTINV. During an arithmetic operation, the floating-point values used in a calculation were invalid for the type of operation requested or invalid exceptional values. For example, when requesting a log of the floating-point values 0.0 or a negative number. For certain arithmetic expressions, specifying the -check nopower option can suppress this message. |
66 | severe (66): Output statement overflows record
FOR$IOS_OUTSTAOVE. An output statement attempted to transfer more data than would fit in the maximum record size. |
67 | severe (67): Input statement requires too much
data

68 | severe (68): Variable format expression value
error
FOR$IOS_VFEVALERR 2. The value of a variable format expression was not within the range acceptable for its intended use; for example, a field width was less than or equal to zero. A value of 1 was assumed, except for a P edit descriptor, for which a value of zero was assumed. |
69 1 | error (69): Process interrupted (SIGINT)
FOR$IOS_SIGINT. The process received the signal SIGINT. Determine source of this interrupt signal (described in signal(3)). |
70 1 | severe (70): Integer overflow
FOR$IOS_INTOVF. During an arithmetic operation, an integer value exceeded byte, word, or longword range. The result of the operation was the correct low-order part. Consider specifying a larger integer data size (modify source program or, for an INTEGER declaration, possibly use the f90 option -integer_size nn ). |
71 1 | severe (71): Integer divide by zero
FOR$IOS_INTDIV. During an integer arithmetic operation, an attempt was made to divide by zero. The result of the operation was set to the dividend, which is equivalent to division by 1. |

77 1 | severe (77): Subscript out of range
FOR$IOS_SUBRNG. An array reference was detected outside the declared array bounds. |
78 1 | error (78): Process killed (SIGTERM)
FOR$IOS_SIGTERM. The process received the signal SIGTERM. Determine source of this software termination signal (described in signal(3) ). |
79 1 | error (79): Process quit (SIGQUIT)
FOR$IOS_SIGQUIT. The process received the signal SIGQUIT. Core dump file created. Determine source of this quit signal (described in signal(3) ). |
95 1 | info (95): Floating-point conversion failed
FOR$IOS_FLOCONFAI. The attempted unformatted read or write of nonnative floating-point data failed because the floating-point value:
Very small numbers are set to zero (0). This error could be caused by the specified nonnative floating-point format not matching the floating-point format found in the specified file. Check the following:
|
96 |
info (96): F_UFMTENDIAN environment variable was ignored:erroneous syntax FOR$IOS_UFMTENDIAN. Syntax for specifying whether little endian or big endian conversion is performed for a given Fortran unit was incorrect. Even though the program will run, the results might not be correct if you do not change the value of F_UFMTENDIAN. For correct syntax, see Environment Variable F_UFMTENDIAN Method. |
108 |
severe (108): Cannot stat file FOR$IOS_CANSTAFIL. Attempted stat operation on the indicated file failed. Make sure correct file and unit were specified. |
120 | severe (120): Operation requires seek ability

138 1 | severe (138): Array index out of bounds (SIGILL)
FOR$IOS_BRK_RANGE. Break exception generated a SIGTRAP signal (described in signal(3)). Core dump file created. The cause is an array subscript that is outside the dimensioned boundaries of that array. Either recompile with the -check bounds option (perhaps with the decfort_dump_flag environment variable set) or examine the core dump file to determine the source code in error. |
139 1 | severe (139): Array index out of bounds for
index nn (SIGILL)
FOR$IOS_BRK_RANGE2. Break exception generated a SIGTRAP signal (described in signal(3) ). Core dump file created. The cause is an array subscript that is outside the dimensioned boundaries of the array index n. Either recompile with the -check bounds option (perhaps with the decfort_dump_flag environment variable set) or examine the core dump file to determine the source code in error. |
140 1 | severe (140): Floating inexact
FOR$IOS_FLTINE. A floating-point arithmetic or conversion operation gave a result that differs from the mathematically exact result. This trap is reported if the rounded result of an IEEE operation is not exact. |

FOR$IOS_STKOVF. The Intel Fortran RTL encountered a stack overflow while executing your program. |
148 1 | severe (148): String length error
FOR$IOS_STRLENERR. During a string operation, an integer value appears in a context where the value of the integer is outside the permissible string length range. Either recompile with the -check bounds option (perhaps with the decfort_dump_flag environment variable set) or examine the core file to determine the source code causing the error. |
149 1 | severe (149): Substring error
FOR$IOS_SUBSTRERR. An array subscript is outside the dimensioned boundaries of an array. Either recompile with the -check bounds option (perhaps with the decfort_dump_flag environment variable set) or examine the core file to determine the source code causing the error. |
150 1 | severe (150): Range error
FOR$IOS_RANGEERR. An integer value appears in a context where the value of the integer is outside the permissible range. |
151 1 | severe (151): Allocatable array is already allocated
FOR$IOS_INVREALLOC. An allocatable array must not already be allocated when you attempt to allocate it. You must deallocate the array before it can again be allocated. |
152 1 | severe (152): Unresolved contention for Intel
Fortran RTL global resource
FOR$IOS_RESACQFAI. Failed to acquire a Intel Fortran RTL global resource for a reentrant routine. For a multithreaded program, the requested global resource is held by a different thread in your program. For a program using asynchronous handlers, the requested global resource is held by the calling part of the program (such as main program) and your asynchronous handler attempted to acquire the same global resource. |
153 1 | severe (153): Allocatable array or pointer is
not allocated
