Defines a string of up to 255 characters System unit
type ShortString
The ShortString type holds sequences of characters up to 255 in length.
Strings can be assigned from other strings, from functions that return a string, and with concatenations as in the sample code.
ShortStrings are indexed with 1 for the first character (arrays start with 0 for the first element).

A String type is treated as a ShortString when the $LongStrings compiler directive is set to Off

Example code : Assigning to a ShortString and a fixed length string
  smallString    : string[2];
  smallishString : ShortString;

  // Assign to our small string
  smallString := 'ABCD';
  ShowMessageFmt('smallString size = %d',[SizeOf(smallString)]);
  ShowMessageFmt('smallString = %s',[smallString]);

  // Assign to our slightly bigger string
  smallishString := 'ABCD';
  ShowMessageFmt('smallishString size = %d',[SizeOf(smallishString)]);
  ShowMessageFmt('smallishString = %s',[smallishString]);
