My question is what does 'EOF' represent.
Explicitly: Are you on the last record or beyond the last record ?

If I open a text file and read until EOF, I know that I have read all chrs/ or lines of the file.
If I try to read one more character or line, vb will throw an error.

But, If I am reading a db table, and I read records until EOF, am I beyond the last record or on it.
If I attempt to read another record, will I get an error or the last record.

I even saw one suggestion on-line that suggested it was different for Client side vs. Server side cursors ?

>>My question is what does 'EOF' represent.

The simple answer is "End Of File" but you already know that. Historically (I remember those from my old mainframe days), it was a real character in a file (just like the End Of Line) and processes were reading the file until they reach that characters. This expression as persisted even if in many cases the character does not exist anymore.

You are past the last record.
