Meaning of GAL+ nomenclature

I have what will likely be a rather naive question. A yeast strain I 
am using has the designation "GAL+" in the genotype description. I 
can't find this described in either the Guthrie and Fink or 
Strathern, Jones and Broach yeast handbooks. My guess is that it 
means the yeast galactose regulon is intact (ie. wild-type GAL4 and 
GAL80 genes) and that this strain can utilize galactose. Is this 
right or hopelessly wrong? It is important as I am planning to 
transform this strain with galactose-inducible expression vector.
Thanking you for your help in advance.
