Qualified Identifiers

When you use an identifier that has been declared in more than one place, it is sometimes necessary to qualify the identifier. The syntax for a qualified identifier is identifier1.identifier2

where identified qualifies identifier2. For example, if two units each declare a variable called CurrentValue, you can specify that you want to access the CurrentValue in Unit2 by writing
