IOSTAT 10008 in opening a file

Good morning, I've a problem not be able to solve. In OPEN a file, I get the IOSTA value of 10008, not documented in Execution errors and IOSTAT values.

Anyone can help me? Thanks in advance.

Remove the IOSTAT from the open statement, let the program crash and see what error message you get.

Thanks John for your answer. In the following case: OPEN( idCLW , FILE=idCLW_NAME ) the message in SDBG debug is: 'Win32 error detected in IO_open : Unknown error'.

Out of debug the message is : 'Access violation: the instruction at address xxxx attempted to read from location yyyy' then a list of routine address.

Note that the opening and closing of the same file has been done at list 5 times before thecrash Have you any ideas?

Ciao John, I've solved the problem, sorry I'm slow... Nothing to do with OPEN, the problem was a vector filled over its dimension. Unfortunatly I was not able to use /CHECK because the usual message: not enough memory ...

Thank you very much for your time
