(the grandma one) the example I gave does this: iif any of the case expressions (they can be arbitrary statements of which the complexity is up to you - as long as they return a boolean) equates to true then you bake a cookie OTHERWISE (the default ;-) you drink beer and watch footy - which given your german email address is rather apt right now :-P I believe that is what you grandma example was aiming at (I used artistic license with the beer and football part :-). > it's one if but not multiple ones (if elseif elseif .. etc.) > > The problem still is it's not that "short" ;) f*** 'short' the time taken to write a line is negligable compared to the time taken to maintain, reread, change, enhance and/or adapt it. try to think in terms of maintainability and readability - and of course performance (the length of a line of code says very little, if anything, about it's performance) - jmho. > > Barry >
