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:
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
