Hallo allemaal, So far all used memory variables, with the exeption of one, remain on their original place in memory as declared by the 1541. The exeption is SAVSP, a temporary storage for the Stack Pointer. I needed four bytes in a row and SAVSP was in the middle of a nice range. As this is a variable that is of no use to a user, I decided to move it. For the LBA filesystem I need more successive zeropage addresses. The question is: how far can I go by moving existing variables? Quite obvious the addresses I should not move are the ones users use to change the device address. But these are the only ones that come in my mind. Are there more addresses I should keep my hands off?
