Returns the access mode or the file access number of a file that was opened with the Open statement. The file access number is dependent on the operating system (OSH = Operating System Handle).
If you use a 32-Bit operating system, you cannot use the FileAttr Function to determine the file access number.

FileAttr (FileNumber As Integer, Attribute As Integer)
FileNumber: The number of the file that was opened with the Open statement.
Attribute: Integer expression that indicates the type of file information that you want to return. The following values are possible:
1: The FileAttr Function indicates the access mode of the file.
2: The FileAttr Function returns the file access number of the operating system.
If you specify a parameter attribute with a value of 1, the following return values apply:
1 - INPUT (file open for input)
2 - OUTPUT (file open for output)
4 - RANDOM (file open for random access)
8 - APPEND (file open for appending)
32 - BINARY (file open in binary mode).
