Control Codes in Numeric Order
Different programs use different methods to send these control
codes to your LX-90. If you use BASIC, you send a control code using
LPRINT CHR$(27) followed by CHR$(n), where n is a number from
the decimal (Dec) 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) or LPRINT CHR§(27)"E"
Some applications programs can use control key codes for decimal
codes O-27. See the control key chart at the end of this appendix for a
complete list of control key values.
