Hi all.

I am getting a "file is in use" or "file is not open" on a simple line of code.

All I'm doing is:

SELECT 6
USE filename

The program crashes on "USE filename" with either of the above two messages.

When I do a DISP STAT just before the SELECT 6 command, this file is definitely not open.

I have, however, noticed the following at the end of the DISP STAT:

Declared DLLs:
GetSystemDirectory C:\WINNT\System32\Kernel32.dll

I'm not completely confident about what a DLL even is, and I certainly haven't declared any (to my knowledge) in my code.

Does anyone have any ideas?

Thanks in advance.

Russell.
