Scott Raney told us once that the engine pre-calculates this 
automatically. I always used to get the number of lines the way your 
example does until I heard that; then I stopped doing it.

Another thing the engine does is abandon an "if" check at the first 
false condition it finds. HyperCard used to check all the conditions 
before it did an evaluation, I think.
