Kinds of Symbols ...

• Arrays: array[1..10] of date
  Store the number of dimensions, lower and upper bound for each, type of array element, number of address units per element.

• Records:
  type vector = record x,y : integer end;
  Store each element name, type, and offset. Variant records simply restart the offset at the start of the variant part.

• Functions and procedures: Store number and types of arguments, result type. Some functions, such as abs ord succ, may be compiled as in-line code.

• Labels: keep in a separate table if they have a form different from symbols.

• Objects: a class in OOP packages together a record of data items and a set of methods, which are procedures associated with the class. In OOP, some form of symbol table for the class is output as well as code for the methods.
