processor usage is wasted **each time** the function is called. memory usage is wasted **when** you store a value in a variable for latter use. better waste memory when there are LOTS of calls to the function/value because then the memory used is the same no matter how many times you need to retrieve the variable's value either one or a million, memory usage will be X bytes and that's it, whereas the processor usage is wasted each time you call the function, but also processor usage is ZERO when the unfction is not used. So it's a question of balance. Easier way is to store the value once and use the variable, nowadays computers got plenty of RAM and many billions processor cycles !! ;-) Cheers, Damien COLA -----Original Message----- Though there is probably no great difference in this one use, would it add up if one style is used alot over another?
