Call Robot ; increases the counter and combines with 00100000b and put it in Px

Robot:
inc count
mov a,count
cjne a,#16,lbl1
mov count,#0
lbl1:
; Combination
mov a,counter
orl a,#00100000b

why not:
clr a
mov p2,#00100000b
loop:
orl p2,a
inc a
jnb acc.4,loop
ret

or if infinite loop is ok:

clr a
mov p2,#00100000b
loop:
orl p2,a
inc a
anl a,#0fh
jmp loop
