It's a handy way of using the A & B variables as local variables when
needed.
.dw $ff03
.db "a>r"
.dw VE_HEAD
.set VE_HEAD = VE_ATOR
XT_ATOR:
.dw PFA_ATOR
PFA_ATOR:
push ah
push al
jmp_ DO_NEXT
.dw $ff03
.db "r>a"
.dw VE_HEAD
.set VE_HEAD = VE_AFROMR
XT_AFROMR:
.dw PFA_AFROMR
PFA_AFROMR:
pop al
pop ah
jmp_ DO_NEXT
Quick and simple definitions which allow you to do stuff like this:
: workwitha
a>r
use a with impunity
r>a
;
I've translated these from my own version, so I hope it's survived.
