The lines in color (I corrected some param mistake) are

(
for(K,1,NRoom),param(T,Timeslots,NCourse)do
     (for(J,1,Timeslots),param(NCourse,T,K)do
          (for(I,1,NCourse),foreach(X,L), param(J,K,T) do
                subscript(T,[I,J,K],X)
           ),
      flatten(L,L1),
      sum(L1)#=<1	<-------
      )
),
  labeling(Vars)		<-------


What do you mean with "whether such red line codes are true or not"?
You could write

	(sum(L1)#=<1
		->	writeln("sum(L1)#=<1 is true")
		;	writeln("sum(L1)#=<1 is false")
	)

and the same for the line with labeling, but it does not make much sense 
(specially for the constraint).

After correcting the mistakes in the loops (see the warnings ECLiPSe 
gives you), the solve(T) goal succeeds, which means that all the 
sub-goals it contains have succeeded.

Cheers,
Marco
