ASM-creating a procedure [closed]

Answer 1

You'd normally want to do a search like this using rep scasb:

test1 proc
    mov P, 0ffffh ; for now, assume it won't be found
    mov al, V                ; what we're going to look for
    mov di, offset array_b   ; where we're going to look
    mov cx, size array_b     ; how many items to search
    repnz scasb              ; do the search
    jnz done                 ; Z flag clear = not found
    sub di, offset array_b   ; found: compute offset into array_b
    mov P, di                ;        and save it
done:
    ret
