Excluding an element from a predefined set in GAMS ?

Question

Over a predefined set S /s1*s100/ I need to write something like this M_s - M_shat =g= 0 , where (shat) is any other element in the set (S) except the element (s). How can I do that in GAMS? Thanks.

You could use an alias set and a conditional with the SameAs operator.

Alias(S,SS);
E_M(s,ss)$(not SameAs(s,ss)).. M(s) - M(ss) =G= 0;
