COMMAND: GOSUB to the subroutine, or GOTO the statement as directed by the result of the
<integer expression>. If the result is 1, then the first line number in the list is chosen, if 2 then the
second etc. In the above line 10, when DAY = 1, the subroutine at line 100 would be visited.DAY =2
would cause a branch to line 200, and so on.
