character, allowing a variety of string manipulation operations. The second version uses CHR to print

individual characters in an ASCII string.

expr

is a decimal number and truncates numbers from 0 through

65535. There must be no space between CHR and the left parentheses or an ARRAY SIZE error results.

expr

can be any integer, printable ASCII characters range from 20H through 7EH (32 through 127).
