Appendix B Control Codes in Numeric Order You can use any of the methods explained in Chapter 4 to send these control codes to your LX-80. If you use MBASIC, you send a control code using LPRINT CHR$(27) followed by CHR$(n), where n is a number from the decimal (Dee) column below. For a few codes, those with a dash in the ESC column, you omit the ESCape code. For the codes above decimal 27, you can use either the character in the symbol column (in quotation marks) or CHR$(n). For example, the command for turning on emphasized can be entered as: LPRINT CHR$(27)CHR$(69)orL,PRINT CHR$(27)"E" See Chapter 4 and your system documentation for other methods of sending codes to the printer. Some applications programs can use control key codes for decimal codes O-26. See the control key chart at the end of this appendix or the Quick Reference Card for a complete list of control key values.

Appendix B
Control Codes in Numeric Order
You can use any of the methods explained in Chapter 4 to send
these control codes to your LX-80. If you use MBASIC, you send a
control code using LPRINT CHR$(27) followed by CHR$(n),
where n is a number from the decimal (Dee) column below. For a few
codes, those with a dash in the ESC column, you omit the ESCape
code. For the codes above decimal 27, you can use either the character
in the symbol column (in quotation marks) or CHR$(n). For exam-
ple, the command for turning on emphasized can be entered as:
LPRINT
CHR$(27)CHR$(69)orL,PRINT
CHR$(27)“E”
See Chapter 4 and your system documentation for other methods
of sending codes to the printer.
Some applications programs can use control key codes for decimal
codes O-26. See the control key chart at the end of this appendix or
the Quick Reference Card for a complete list of control key values.
