Short Note on Forward Reference
Forward Reference :- A forward reference of a program entity is a reference to the entity which precedes its defecation in the program.
While processing a statement containing a forward reference a language processor does not passes all relevant information concerning the referenced entity. This creates difficulties in synthesizing the equivalent largest statement. This problem can be solve by postponing the generation of target code. Until more information becomes available postponing the generation of target code reduce memory requirement of the language processor and simplify its organization.
