Great, thanks Taco! It works. It seems easier than I thought, but I
could have spent hours looking for the proper solution alone.

I hope this will land in the t-rsteps module (\OnSteps[1,2,3,6]{...}).

Well, my stomach needs some time to process the latter example. But if I write
    \def\IHaveToDoTheTask[#1]#2{\message{(#1: #2)}The task #1 has to
be done #2.\crlf}
    \IHaveToDoTheTasks[1-3]{until tomorrow}
nothing happens.

Thanks again,
