Re: [Quickfix-developers] compatible questions

Alvin,
you won't be able to pass along a FIX 4.2 message directly into a system 
expecting a FIX 4.4 message but you could write an app that has two 
sessions, a 4.2 and a 4.4 and some code in between that does the 
conversion.  What conversion is necessary will depend on what you're 
trading.  Fields are added and removed between versions.
