hey there.

i am using ATL and i have done the following

helper def : sequenceofcomp : Sequence(String)= Sequence {'oven','powertube'};
helper def : sequenceofbehavior : Sequence(String) = Sequence {'open', 'off'};

helper def : first: Sequence(String) = thisModule.sequenceofcomp ->
collect(c|c.concat(thisModule.sequenceofbehavior -> collect(b|b) ) ) -> iterate(s; seq:Sequence(String) =
Sequence{}| seq.append(s));

the output of this is oven[open,off] and powertube[open,off].
What i want is that oven gets concatenated with open and off and powertube gets concatenated with open and off in a sequence

how can i achieve this

Thanks in advance

Hi

Once you express your desire as an algorithm, you should be able to
express it in OCL.

So try re-expressing, avoiding non-algorithmic English such as

"oven gets concatenated with open"

Why 'oven', why 'open' ?

Once you answer these questions as an iteration your problem is solved.

Hint: Sequence{1..x->size()} is a convenient way of constructing a loop
variable over x.

Regards
