#3 Chr, Ord, Succ, Pred functions

[Philippe Majerus]

It would be nice to have Pascal's Chr, Ord, Succ and Pred functions, making it possible to handle special characters, insert newline and pagefeeds in strings and other characters-related manipulations.

const BS = 8;
TAB = 9;
LF = 10;
VT = 11;
FF = 12;
CR = 13;

var st1 : string;
st1 := 'hello'+ chr(CR) +'world';
