An identifer is a symbol used in a Pascal program which consists of letters, numbers and certain special characters, used to indicate a specific variable, constant, object, record, type, procedure or function.

For example, in the following piece of code: 

Program WittsEnd;
Const Y=2;
Var Plugh: Integer;

   Procedure Xyzzy;
   begin
   end;

Begin
   Plugh := Y*2;
end.

we can say that

  • WittsEnd
  • Y
  • Plugh
  • Xyzzy

Are all identifiers.
