What happened to EOF()

[ferrad1]

I have used this function to determine the end of file in Intel Fortran for many years:

if( .not. eof(lno)) ...

Now I am getting an error.

error #6410: This name has not been declared as an array or a function. [EOF]

Has it been removed from Intel Fortran?

IS_IOSTAT_END

Elemental Intrinsic Function (Generic): Tests for an end-of-file condition.

result=IS_IOSTAT_END(i)

eof function is non-standard but I think still exists, do you have standard checking options on?

[ferrad1]

I have these checks on.

/check:pointer /check:bounds /check:uninit /check:arg_temp_created /check:stack

Additional:

Compiling with Intel® Fortran Compiler Classic 2021.8.0 [Intel(R) 64]...
... warning #7416: Fortran 2018 does not allow this intrinsic procedure. [EOF]

but without standards it compiles ok so I have no clue what is going wrong.

[ferrad1]

Must be some option.  Will try from a raw project and creep up on it.

you can try the sample from the dev guide:  https://www.intel.com/content/www/us/en/develop/documentation/fortran-compiler-oneapi-dev-guide-and-reference/top/language-reference/a-to-z-reference/e-to-f/eof.html

It is an extension, not standard, so the standards warning is valid. Ron gave a pointer to the documentation.

Note that IS_IOSTAT_END that Andrew mention tests an IOSTAT value, you don't pass it a unit number.
