begin
  myChar := 'G';                    // Assign from a character constant
  WriteLn('Letter G = '+myChar);

  myChar := #65;                    // Assign from an integer constant
  WriteLn('#65 = '+myChar);

  myChar := ^I;                     // Assign from a control char - tab
  WriteLn('Control '+myChar+' character');

  myChar := Chr(66);                // Using Chr to convert a number
  WriteLn('Chr(66) = '+myChar);

  myChar := Char(67);               // Using Char as a standard cast
  WriteLn('Char(67) = '+myChar);
end;
