 CHR()
 Convert an ASCII code to a character value
------------------------------------------------------------------------------
 Syntax

     CHR(<nCode>) --> cChar

 Arguments

     <nCode> is an ASCII code in the range of zero to 255.

 Returns

     CHR() returns a single character value whose ASCII code is specified by
     <nCode>.

 Description

     CHR() is a numeric conversion function that converts an ASCII code to a
     character.  It is the inverse of ASC().  CHR() serves a number of common
     tasks including:

     .  Sending control codes and graphics characters to the screen or
        printer

     .  Ringing the bell

     .  Converting INKEY() return values to characters

     .  Stuffing the keyboard buffer

 Notes

     .  The null character: CHR(0) has a length of one and is treated
        like any other character.  This lets you send it to any device or
        file, including a database file.

 Examples

     .  These examples illustrate CHR() with various arguments:

        ? CHR(72)                   // Result: H
        ? CHR(ASC("A") + 32)        // Result: a
        ? CHR(7)                    // Result: bell sounds

     .  These lines of code show the difference between a null string
        and the null character:

        ? LEN("")                   // Result: 0
        ? LEN(CHR(0))               // Result: 1
