Returns the character for a specified ASCII value.

Chr returns the character with the ordinal value (ASCII value) of the byte-type expression, X. The Byte parameter is an unsigned integer value large enough to represent a character. Word or UInt16 is also appropriate, because now that the string type is Unicode, a character is represented by two bytes.

Example
TRObject Syntax

 var
   tab  : char;
   crlf : string;
 
 {
   // Show the use of Chr
   tab = Chr(124);
   crlf = Chr(13)+Chr(10);
   ShowMessage('Hello '+tab+' World');
   ShowMessage('Hello'+crlf+'World');
 }

Base Syntax

 var
   tab  : char;
   crlf : string;
 
 begin
   // Show the use of Chr
   tab := Chr(124);
   crlf := Chr(13)+Chr(10);
   ShowMessage('Hello '+tab+' World');
   ShowMessage('Hello'+crlf+'World');
 end;
