-====== How do I use the matching operator? ====== 
-Q: I have ''​ SET   c com / c1*c10 /; ALIAS (c,​c1);''​ and I would like to have a kind of  compatibility matrix, i.e. if comp('​c1','​c8'​) = yes, 
-then the two elements are compatible. I would like to use statements such as ''​comp(c1*c4,​ c8*c10) = YES;'' ​ 
- 
-This can easily be achieved using the matching operator: 
-<​code>​ 
-SET        c com /c1*c10 / 
-ALIAS (c,c1); 
-SET comp(c,c1) /​c1*c4:​c8*c10/;​ 
-display comp; 
- 
-----      4 SET comp  ​ 
-            c8          c9         c10 
-c1         YES 
-c2                     YES 
-c3                                 YES 
-</​code>​ 
-
