CHR
Use the CHR operator to convert a numeric expression to an ASCII
character.
>PRINT CHR(65) Result: A
Like the ASC operator, the CHR operator also selects individual characters
in a defined ASCII string. The expressions within the parentheses that
follow the CHR operator have the same meaning as the expressions in the
ASC operator.

Unlike the ASC operator, you cannot assign the CHR operator a value.
A statement such as CHR ($(1),1)= H is invalid and generates an
ERROR:
BAD SYNTAX message,. When this error occurs the BASIC module enters
Command mode. Use the ASC operator to change a value in a string, or
use the string support CALL 65 (page 12 -64) - replace string in a string.
Important: Use CHR only in a PRINT statement (page 11 -29).
You cannot use the CHR in a DATA statement (page 11 -6).
