Seem to remember more control over >some things like this, though it's almost 3 years now since using it. ASC's Sequel doesn't support the TO_NUMBER function as such, but it does provide the ability to do this task. There is a ZONED function which converts a (normally character) expression into an AS/400 zoned number, which can then be converted to packed or integer or floating point. It's all very AS/400-eccentric and decidedly non-portable, of course. It works great, though - we've used it several times.
