Hello Everybody,
Nee some help about this.

There is an array on RAM addresses 0x20 - 0x6F.
I have also an array a portion of bank1 and the whole bank2 and bank3.
The only free locations on the 877A are the locations A0 to B2 on Bank1
I already used up the RAM 0x70 - 0x7F (because these RAM locations do not require banking).

How do i declare a variable to be located at say for example address 0xA0? is it just

DUMMY equ 0xA0

Thanks

JAck
