- * ir representation of a program.
+ * Intermediate Representation (IR) of a program.
*
* This file defines a construct that keeps all information about a
* program:
* - A reference point to the method to be executed on program start.
* - A list of all procedures.
* - A list of all types.
- * - A global type that contais all global variables and procedures that do
+ * - A global type that contains all global variables and procedures that do
* not belong to a class. This type represents the data segment of the
* program. It is not the base class of
* all classes in a class hierarchy (as, e.g., "object" in java).
