Hi Sayzer. Well, now there is no official directive as to where is better placed a sub. According to old practice, on top. But this does not affect in any way the execution.

I only pointed out that if one has 5 sub's for example, and have different sizes, rearranging the order of them is affecting the final code size. I think is because a bigger sub might fall between two pages while others won't.

After a little experimenting you can find that your code might reduce up to 20% or more! Also if you change your variables to be placed on BANK0 also may help. Especially if there are arrays in the program. I had a program reduced from 7540 bytes to 6200 using the above!
