CHR()

    CHR() returns a character from the IBM Extended Character Set.

Syntax

    CHR(<exp N>)

Argument

    <expN> is the IBM Extended Character Set code of the character to
    return and can be in the range of zero to 255.

Returns

    A character value.

    CHR() returns the character corresponding to the IBM Extended Character
    Set code.  Note that different commands treat characters in different
    ways.  For example, @...SAY CHR(7) displays a graphic character to the
    screen whereas ? CHR(7) sounds the bell.

Usage

    CHR() enables you to send control codes to the printer.  Another
    typical application is to produce special effects on a printer and/or
    monitor by sending a value in the IBM Extended Character Set for any
    keyboard character or graphics character.  Another typical application
    is to use CHR() to ring the bell alerting the user of an error.

    A more sophisticated application is to control the keyboard.
    Typically, you use CHR() in combination with KEYBOARD to stuff the
    keyboard with key codes.  In some instances, you might find it useful
    to create key names by assigning the CHR() of the key code to a memory
    variable.  Later, you can compare the result of a CHR(INKEY()) to the
    key name variable.

    BNote: CHR(0) now has a length of one and is treated the same as any
    other character.  This allows you to send it to any device or file,
    including a database file.
