What is "forrtl: severe (104)" ?

[bgirl_02]

I got this error in linux(Ubuntu 8.04 hardy).
forrtl: severe (104): incorrect POSITION= specifier value for connected file, unit 19 .........

I also tried ACCESS insted of POSITION but same kind of error came out.
forrtl: severe (104): incorrect ACCESS= specifier value for connected file, unit 19 .........

I compiled by ver. 10.0.023 for linux.

Can you post the relevant source lines (the one where you open the file?) What are you feeding POSITION with? Generally I only specify it when I want to apped stuff to the file (like POSITION='append' ). And... do you have permissions to write the file (just checking).

Agreed: we need to see your OPEN statement for unit 19 and the READ or WRITE where this occurs.

You can compile and link with -g -traceback to find the exact source line where you crash.

Thanks both of you. This is open and write statement.

OPEN (19,access='append',FILE='NEW_SOUR',STATUS='unknown')
or OPEN (19,FILE='NEW_SOUR',position='append',STATUS='unknown')

WRITE (19,*) NAME, ' ', expid

Also I own the file and I have write permission as you see below.

The error was normally caused by openning the same file multiple times with inconsistent POSITION specifier. For example in your case if you have already opened the non-null file with "POSITION=REWIND" and then try to reopen it with "POSITION=APPEND" you will get such error.

you maybe right, bgirl_02, are you sure you don't have two open statments for the same file?

grep -ni OPEN *f90

would give you all the opens you use in your code...

I could not find the problem, which you said, in the sources.

Actually this is not my code. The execution binary, which was compiled somewhere, worked before.
I just changed one line and, after compilation, the error came out.
So I compiled original source again, and then, the same error also came out.

By the way, I compiled same source in aother PC with 9.0 version.
Do you think this runtime error came from compiler or library?

can you compile it with gfortran, just in case ? which flags are you using?

Sorry for late.

After compiling with gfortran, when I run the execution file, following errors came out.

At line 844 of file dtau0.f
Fortran runtime error: Cannot change STATUS parameter in OPEN statement

Line 844 is same line which caused the error before.
OPEN (19,access='append',FILE='NEW_SOUR',STATUS='unknown')

I compiled like this

gfortran -o dtau0 dtau0.f subroutinefiles...

This is also indicating that file 19 is already open by the time you get to this statement. You could try this:

close(19)
open( 19,access='append',file='NEW_SOUR',STATUS='unknown')

Thank you so much.
I think it works!
I also appreciate everybody's comment.

Thnx a lot, even I wanted an answer for the same...
