Try this bit of self-modifying code:

     ld hl,addr               ; the address we want to call
     ld (callman+1),hl    ; override the FFFF
callman:
     CALL_($FFFF)        ; call the address (FFFF overwritten)

I think that should work in ZShell, but I'm not sure :) Remember to update the
checksum before you leave tho.
