# $EPIC: chr,v 1.2 2003/07/07 05:24:17 jnelson Exp $
Synopsis:
   $chr(<integer list>)

Technical:
   This function converts a list of integers, formatted as:
	0x<num>		as a hexidecimal (base 16) number
	0<num>		as an octal (base 8) number
	<num>		as a decimal (base 10) number
   into a string of characters, where each integer in the list comprises
   each character in the output string, in order.

   <num> should be the equivalent of a decimal number between 0 and 255
   inclusively.  Precisely, only the 8 least signficiant bits are used in
   each number; any higher bits are ignored.  For negative numbers, this
   means you should keep adding 256 to the number until you get a
   nonnegative value.

   Because your font determines what glyphs (characters) appear at each 
   ascii position, the return value may appear differently depending on 
   your current locale.

Practical:
   It is not necessarily obvious that it is not necessary to encode an
   entire string using $chr().  It is possible to insert only one 
   character, and it is very handy in places where inserting a control
   character would be a hassle.  For example, $chr(3) inserts a ^C which
   is the color-shift control character.

Returns:
   chr:   concatenated list of characters.

Examples:
   /* assume iso8859-1 character set */
   $chr(1 2 3)                        returns "ABC" (ctrl-A, -B, -C)
   $chr(3)4Hey!                       returns "Hey!" in red
   $chr($ascii(abcABC))               returns "abcABC"
