To convert an ASCII code to its equivalent character.
n is a value from 0 to 255.
CHR$ is commonly used to send a special character to the terminal or printer. For example, you could send CHR$(7) to sound a beep through the speaker as a preface to an error message, or you could send a form feed, CHR$(12), to the printer.
See the ASC function for ASCII-to-numeric conversion.
ASCII Codes are listed in Appendix C of the GW-BASIC User's Guide.
