CHR is a dual use ope rator, similar to AS C. One ve rsion converts a nu meric exp ression to an A SCII
character, allowing a variety of string manipulation operations. The second version uses CHR to print
individ ual ch aracte rs in an A SCII s tring. expr is a decimal number and truncates numbers from 0 through
65535 . There must be no s pace betw een C HR and th e left pa renthe ses or a n AR RA Y SIZ E erro r results .
Although expr can be any in teger, printable AS CII characte rs range from 20 H through 7E H (32 through 127).
The STR function may be used to m anipulate and print longer portions of strings.
