Isn't language a wonderful thing. Or syntax, if you prefer. Look very, very carefully at the bits before "Identifier" in that help page. Now think, where do I use those keywords "DIM" and "PRIVATE" when declaring a variable (or a constant for that matter). Got it? No? Class Frog Static Private maxlegs as Integer Private legs as integer Public Sub _new(iLegs as Integer) Dim mylegs as Integer If iLegs<=Frog.maxlegs then mylegs=iLegs legs=mylegs Endif End Static Public Sub _init() maxlegs=3 End If the above hasn't got frogs legs, eggs and whatever dancing before your eyes, go back and look at each of the 37 words. It may take some practice.... it's taken me about 3 years :-) Bruce ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
