I tried it and it says:

	[eclipse 2]: solve(0,6).

	No (0.00s cpu)

what do you mean by "it hangs"?

You question on "what is the query" is like asking: how should I invoke 
this C (or Java, Pascal, whatever) function I downloaded from the net?

Well, it should be in the documentation of the code you downloaded. If 
it is not, then you should look at the code and try to understand what 
this code does.

Looking quickly at the code, I guess that:
Predicate data contains the input data.
Predicate model contains the constraint model.
Predicate optimize is predefined in the eplex library, so you can read 
the ECLiPSe documentation.
The final row prints the output.

So, it seems to me that Cost and Slots are output parameters in this 
code, so they should be variables:

[eclipse 3]: solve(Cost,Slots).

Yes (0.03s cpu)

As far as I understand, the input data is in predicate data.
Change that predicate according to your instance.
