Fortran 95 Runtime Error
Contents |
a detailed description of the error. To define the condition symbol values (PARAMETER statements) in your program, include the following file: for_iosdef.for As described in the table, the severity of the message determines which gfortran iostat of the following occurs: with info and warning, program execution continues with error, the fortran error codes results may be incorrect with severe, program execution stops (unless a recovery method is specified) In the last case, to prevent fortran runtime error end of file gfortran 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. In the following table, 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$IOS_INCRECTYP) and an explanation of the message. Number Severity Level, Number, and Message Text; Condition fortran error handling Symbol and Explanation 11 severe (1): Not a Fortran-specific error FOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not an Intel Fortran-specific error and was not reportable through any other Intel Fortran run-time messages. 8 severe (8): Internal consistency check failure FOR$IOS_BUG_CHECK. Internal error. Please check that the program is correct. Recompile if an error existed in the program. If this error persists, submit a problem report. 9 severe (9): Permission to access file denied FOR$IOS_PERACCFIL. Check the permissions of the specified file and whether the network device is mapped and available. Make sure the correct file and device was being accessed. Change the protection, specific file, or process used before rerunning the program. 10 severe (10): Cannot overwrite existing file FOR$IOS_CANOVEEXI. Specified file xxx already exists when OPEN statement specified STATUS='NEW' (create new file) using I/O unit x. Make sure correct file name, directory path, unit, and so forth were specified in the source program. Decide whether to: Rename or remove the existing file before rerunning the program. Modify the source file to specify different file specification, I/O unit, or OPEN statement STATUS. 111 info (11): Unit not connected FOR$IOS_UNINOTCON. The specified unit was not open at the time of the attempted I/O
system call failures, C library errors, and shell diagnostics. The system call error messages are found in intro(2). System calls made through the Fortran library do not produce error messages directly. The following system routine in the Fortran library calls ls dyna error part out of range C library routines which produce an error message: CALL SYSTEM("rm /") END The following

message is displayed: rm: / directory Signal Handler Error Messages Before beginning execution of a program, the Fortran library sets up a
Intel Fortran Runtime Error Codes
signal handler (sigdie) for signals that can cause termination of the program. sigdie prints a message that describes the signal, flushes any pending output, and generates a core image and a traceback. Presently, the only arithmetic http://geco.mines.edu/guide/Run-Time_Error_Messages.html exception that produces an error message is the INTEGER*2 division with a denominator of zero. All other arithmetic exceptions are ignored. A signal handler error example follows, where the subroutine SUB tries to access parameters that are not passed to it: CALL SUB() END SUBROUTINE SUB(I,J,K) I=J+K RETURN END The following error message results: *** Segmentation violation Illegal instruction (core dumped) I/O Error Messages (f77) The error messages in this section are generated http://northstar-www.dartmouth.edu/doc/solaris-forte/manuals/fortran/user_guide/A_messages.html by the Fortran 77 I/O library. The error numbers are returned in the IOSTAT variable if the ERR return is taken. For example, the following program tries to do an unformatted write to a file opened for formatted output: WRITE( 6 ) 1 END and produces error messages like the following: sue: [1003] unformatted io not allowed logical unit 6, named 'stdout' lately: writing sequential unformatted external IO The following error messages are generated. These same messages are also documented at the end of the man page perror(3F). If the error number is less than 1000, then it is a system error. See intro(2). TABLE A-1 f77 Runtime I/O Messages Error Message 1000 error in format Read the error message output for the location of the error in the format. 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. Negative unit numbers are not allowed. The upper limit is 231 - 1. 1002 formatted io not allowed The logical unit was opened for unformatted I/O. 1003 unformatted io not allowed The logical unit was opened for formatted I/O. 1004 direct io not allowed The logical unit was opened for sequential access, or the

I'm trying to write a function that will integrate a user given function. I am having trouble with reading the function. Here is a section of my code: function f(x) implicit none https://groups.google.com/d/topic/gg95/cA0j0MpJG2w real :: x,f,p print *,'Type a probability density function' read *, p !It doesn't like line 34... f = p end function f It compiles fine, but then when I run the program and enter a function runtime error (say, x**2), it gives me the error: Fortran runtime error: Bad real number in item 1 of list input Help, please! ngendler, Jun 17, 2013 Phys.org - latest science and technology news stories on Phys.org •Game over?

Fortunately in your case, almost every parsing solution (e.g. lex/yacc resp. flex/bison) has a calculator as standard example, so you can take such a sample and refine that according to your needs. Solkar, Jun 17, 2013 Jun 17, 2013 #3 Borek Staff: Mentor Are you sure your program is expected to parse the function entered manually by the user on the prompt, and not given in an external file compiled together with your program? The latter is a rather standard assignment on many programming courses. Borek, Jun 17, 2013 Jun 17, 2013 #4 ngendler @Borek, yes I am sure. I want the user to be able to say "x**2" and have the program read it and integrate it. ngendler, Jun 17, 2013 Jun 17, 2013 #5 SteamKing Staff Emeritus Science
