Yeah, and this is exactly the reason why I stopped on expressions. There 
is no way to distinguish beween a pchar and a string "string"

FName[1] (where FName:PChar) has a complete different meaning than 
FName[1] (where Fname:String)

it works, but does it show the correct value ?

It is quoted iirc (or did I forget it somewhere ?).
