Is this the expected behavior with "default" ?

[Domingo Alvarez Duarte]

Hello !

With the GMPL model below when we ask to display an entity with a 
declared "default" value we get nothing but if we indirectly reference 
then  we get the "default" value.

====

param Jm, default 3;
set J := 1..Jm;

display Jm;
display J;
display Jm;
====

Output:

====

...

Display statement at line 3
Jm has empty content
Display statement at line 4
J:
   1
   2
   3
Display statement at line 5
Jm = 3
...

====

Cheers !
