Philip,

With the Metalink assembler just use the statement "data" i.e.

save_data data 30H
save_number data 31H

you can now use it as a variable

i.e.

mov save_number,#FFH

also if you need bit storage (found between 20H and 30H

use the "bit" statement

i.e.

save_bit equ 20H.0
save_sign equ 20H.1

now use it as bit variable


jb save_bit,where_ever

or

mov c,p1.7
mov save_sign,c
