The character function gives yOll the character corresponding to the
ASCII character code specified in the argument. The argument is
the value obtained when the numericexpression is evaluated. The
normal rules for the evaluation of numeric expressions are used
here. If the argument specified is not an integer. it is rounded to
obtain an integer. A list of the ASCII character codes for each
character in the standard character set is given in the Appendix.
If the argument specified is a value between 32 and 127.
inclusive. a standard character is given. If the argument specified
is between 128 and 159. inclusive, and a special graphics
character has been defined for that value. the graphics character
is given. If you specify an argument which designates an
undefined character (i.e. not a standard character or a defined
grRphir.s r.hRrHctP:r), thp:n thp: chRrHctf'r p;ivp:n is wha IP:VP:f is in
memory at that time.
If you specify a value for the argument which IS less than zero or
greater than 32767, the message "BAD VALUE'" is displayed, and
the program stops running.
