RTTI can be utilized to obtain a number of meta information in a Pascal application.

Converting a enumerated type to a string

One can use RTTI to obtain a string from a enumerated type.

type
  TProgrammerType = (tpDelphi, tpVisualC, tpVB, tpJava) ;

uses TypInfo;

var 
  s: string;
begin
  s := GetEnumName(TypeInfo(TProgrammerType), integer(tpDelphi));
  // Here s = 'tpDelphi'
