My idea for a data stack. high byte and low byte on two 256 byte stacks managed by 1 stack pointer.
PushD: ldx stackP //push .a and .y to our 2 byte stack
dex
sta lowStack,x
tya
sta highStack,x
stx stackP
rts
PopD: ldx stackP //pop .a and .y from our 2 byte stack
lda lowStack,x
ldy highStack,x
inx
stx stackP
rts
