Minerva Bug?

On occasion, I attempt to translate a program, written as “spaghetti code” in one of the several primitive Basics, into SuperBasic. Where the author has left little or no room between lines, it becomes necessary to renumber the program in order to get some working room. In the course of one such attempt, I encountered an interesting feature (read that, “bug”) in Minerva’s handling of GO TO and GO SUB.
