- paul666 But 8.0 is seven years old now - you might want to consider upgrading. Yes, I know, it's an "oldie but goodie," and I've 8.0 stuff around myself.
- tcl8.0 is part of the fidessa product  which is a leading cash equity / front office product installed in most of the banks in the city in the UK...
- paul666 - ok, if you've 8.0-dependent installed base, then play the hand you're dealt.
