In this case EOF never becomes true, it just remains at false after
it reaches the end of the rows and gets stuck on the last row.

I want it to return false after the first "Next" call on the last
row. I think this is normal behavior, but I'm am only learning C/S
now in combo with Firebird and IBO.

My problem stemmed from running a report when I was exporting the
rows to an HTML table. It never exited to EOF loop, so I wrote the
code snippet I posted which never exits as well.
