Appendix A - Character Sets and Keywords Introduction to Character Sets The following information applies to all single-byte character sets: • Characters between ASCII 00 decimal and ASCII 31 decimal are unprintable control characters as listed below. • Characters between ASCII 32 decimal and ASCII 127 decimal can always be printed, regardless of 7-bit or 8-bit communication protocol, provided that the selected font contains those characters. • Characters between ASCII 128 decimal and ASCII 255 decimal can only be printed if the selected font contains those characters and an 8-bit communication protocol is used. If you use 7-bit communication, select another national character set with the NASC command, or use a MAP statement to remap a character set. • If a character which does not exist in the selected font is used, an error condition occurs.
