To make the program asm, you need to put $8e28 at the start of your
code:

 ld hl,op_info
 rst 20h                ;[sqrt]KEY -> OP1
 ld hl, code_end - code
 call $474f            ;creates program
 ld a,b
 ex de,hl
 call _SET_ABS_DEST_ADDR
 xor a
 ld hl,code_end - code
 call _SET_MM_NUM_BYTES
 xor a
 ld hl,code
 call _SET_ABS_SRC_ADDR
 call _mm_ldir

 res 6,(iy+24)       ;enables program
 ret

op_info:
.db $12,$4,$10
.db "KEY",0

code:
.db $8e,$28
 call $479f

;code here

 cp a
 ret
code_end:

This creates the program nicely, but the code still won't work and just
makes the menus screwy.  There's probably a second flag that needs to be
set.
