Section 11. String Functions

CHR(c)

The CHR string function returns an ANSI character. 'c' ranges in values from

0..255.

The character returned by the CHR function can be stored in a string in the

program or sent to some other device by using such instructions as EmailSend

or SerialOut.

ANSI characters for decimal codes 0 through 128 are shown in Table 11.1.

See the editor for ANSI characters for decimal codes 129 through 255.
