Reading an open file (When opened for append)

[Lance Edmonds]

If the file is already opened with LOCK READ WRITE (from elsewhere in your code or even in another process) then you will not be able to open that file.

However, if you have the PB file handle, you can test the file mode (APPEND, etc) with FILEATTR(), but FILEATTR() cannot determine the lock mode.

If I have a program that MAY or may not be opened for append (I won't know), is there a way to safely detect it?
I mean I could do a function and test for it but I want to read the contents of a file that is opene append lock read write


Can it be done? I'm getting weird errors trying it now, I know the file exists, I test for existence, but if the file is opne I get an error 53 (not found)..
