Setting "it" is the easy part. Convincing the compiler to accept "it"
after a command is hard.

on DarzCommand
  do "put 123 into it"
  -- now 123 is in both it and the result
  return it
end DarzCommand

on mouseUp
  DarzCommand
  put it -- this will give a compiler error
end mouseUp

...while...

function DarzCommand
  do "put 123 into it"
  -- now 123 is in both it and the result
  return it
end DarzCommand

on mouseUp pMouseBtnNo
    get DarzOwnVersionOfAsk(13)
    if it is 123 then
        put "yep"
    else
        put "nope"
    end if
end mouseUp

works as designed.
