I had a look at the mailing list but it comes up as read-only for me for 
some reason?
I am logged in to Source Forge but haven't used it much

as for the news group I subscribed to it (it appears in the list of 
available news groups) but when I try to access it I'm told it doesn't 
exist on the server ??

I can send a stripped down code (it'll take a while to put it together 
so it'll be next week some time)
3 question on that
1) Would you prefer a direct mail with it or an atachment to the NG?
2) Do you need tgz or is zip fine?
3) Is a VC project file fine to show the compile setting I am using?

I'm running a P3 866, 512M Ram, NT4 SP6

This is another developers code but I made the call to use Spirit so I 
have to do the optimising !
so please bear with me if it takes a while for me to split it off :(

That seems obvious now that you say it
I was thinking in terms of spliting spirit off which causes problems but 
, as you say, all I need is to build a lib with my parser in so that 
spirit is hidden.

        Thanks for the quick response, Vin
