+"0BRANCH" is a function word that implements execution conditional by
+means of optionally adding the subsequent branch offset, or not, to
+the point of execution. If the value, v, is 0 then the branch offset
+is added, and otherwise execution continues with the cell following
+the branch offset in the definition.
