It's not nescessarilly a code-space 'problem'. Sometimes in one sequence, PICBasic squeezes a variable (which just happens to be frequently used) into Bank Zero, and you get a tight code-space compilation. You add a couple of variables later, recompile, and now this variable might no longer be in Bank Zero, but is pushed into Bank 1, and suddenly your program code usage is heaps bigger.

Naturally you jump to the conclusion that shuffling the variables in different sequences varies the code-space used... but it's not the variables themselves, but how they are subsequently accessed that changes the amount of bytes compiled.

So going back to your original thread starter... yes, there IS a speed and memory advantage... the advantage is in getting your most frequently used variables stored into Bank Zero - it makes a BIG difference if you're optimising for performance and code-space.
