As far as I know, the POV SDL *does* make this assumption. You missed 
his point...there is no way of knowing the end of the block is at the 
end of the file. It has to search to find the matching #end, and it has 
to do this starting forward from the #if statement. You can't even 
search backwards from the end of the file, you will mess up if you have 
multiple #if statements in series, and you can't just stop at the first 
#end, or you mess up nested statements.
