Iostat 29 fortran error

[SoleLabMec]

Hi, I'm running a subroutine in Fortran and I need to open a data file, i use this statement:

OPEN(unit=101,file='sdvh.inp',status='old',iostat= nopath)
READ(101,*) ((SDVH(I,J),J=1,NCOL),I=1,NELEMH*NGPH)
CLOSE(unit=101,status='keep')

And I keep having a iostat=29, can anybody tell me why? The file is in the same directory as the program and if I run this subroutine in Fortran in Windows I don't have any problem.

Thanks for your help.

Hi.

Welcome to the forums.

I wrote a complete program incorporating your excerpt, created a small dataset, then compiled and ran it on Debian Sarge with f77/g77 (3.3.5), and also on Debian Lenny with gfortran (4.3.2).

It failed on Sarge until I changed the unit number from "101" to "9" (with the help of an error message). It worked without changes on Lenny.

In order to get more responses (say for future questions), I suggest you post the smallest complete example of a program, along with a minimal dataset. Noting your infrastructure would also be useful -- OS and versions of compilers, etc. That will allow responders to concentrate on solving your problem, rather than constructing a framework within which to test your code.

Best wishes ... cheers, drl
