Printing Text With Delta 33

twice, but they use slightly different methods to darken the char- acters. Let’s try them and see what the difference is.

The following table shows the control codes for getting into and out of double-strike and emphasized modes.

		Table 3-3
	Print	emDhasisa	commands
Function			Control	code
Double-strike	ON		‘,ESC)	“G”
Double-strike	OFF		(ESC)	“H”
Emphasized	ON		(ESC)	“E”
Emphasized	OFF		(ESC)	“F”

Try them now with this little program:

NEW

18 LPRINTCHR$(27)"G"

28LPRINT "THIS IS DOUBLE-STRIKEPRINTING"

3p LPRINTCHR$(27)"H" CHR$(27)"E";

4@ LPRINT "THIS IS EMPHASIZEDPRINTING" 5!2 LPRINTCHR$(27)"G";

69LPRINT "AND THIS IS BOTH AT ONCE" 7pILPRINTCHR$(27)"H" CHR$(27)"F"

Run this program. The results will look like this:

THIS IS DOUBLE-STRIKE PRINTING

THIS IS EMPHASIZED PRINTING

AND THIS IS BOTH AT ONCE

Line 10 turns on double-strike with (ESC) “G” and line 20 prints a line of text. In line 30 double-strike is turned off with (ESC) “H” and then emphasized is turned on with (ESC) “E”. Line 40 prints a line of emphasized text. Line 50 then turns dou- ble-strike back on so that line 60 can print in both at once. Finally, line 70 turns both off, so that Delta is set for normal printing.

Look closely at the different lines of printing. In the line of double-strike printing each character has been printed twice, and they are moved down just slightly the second time they are
