Using FileMaker as ODBC Source

According to the dictionary entry for revOpenDatabase, you need to use the
cursortype parameter for ODBC connections. The defualt is "forward only"
which does not support the use of revMoveToFirstRecord,
revMoveToLastRecord, and revMoveToPreviousRecord.
It looks like a cursortype of "emulated static" will work for what you need
I couldn't quite figure out what you are trying to do by going to the last
record but if you just need to know how many records are in the cursor, you
can use revNumberOfRecords(theCursor) instead of going to the last record
