z80 assembler issues with "IM 1" instruction

Code

STACK .EQU 2099H
.ORG 0000H
    ld  SP, STACK
    jp 2000H

.ORG 0038H
    jp  service_routine

.ORG 2000H
    EI
    IM 1 ; <------- THIS LINE 
    LD  A, 00H

LOOP:
    ADD A, 00H
    jp  z, LOOP

service_routine:
    DI
    ld  A, 55H
    out (07H),A
    ld  A, 00H
    EI
    ret

Error

Using this online IDE http://clrhome.org/asm/

It gives me: Unknown instruction or directive IM (line " IM 1" in hello_z80)

So?

Am i doing something stupid here?

I have no clue as to why i get this error.

Haven't had any luck with google.

As I said in the comments, I've let DeepThought know about it. I just hopped on the chat at Omnimaga (DeepThought is an admin there), and he told me he has fixed it.

IM 0, IM 1 and IM 2 all work now. They assemble and autocomplete knows about them too.

So in answer to your question, yes, it was in fact a bug and not your fault.
