12.3.1 Compile-Time Decisions

Decisions made at compile time include where to put information and how to get it. These are the same decisions made about symbol tables (see Exercise 5), but here the information is different. For symbol tables, we are concerned about information that is known at compile time, in particular the symbol's class. Here, we are concerned about information not entirely known at compile time, such as a particular symbol's value or how many instances there will be of a variable due to recursive calls.
