Try them now with this little program:
10 ' Demo of boldface and emphasized
20 LPRINT CHR$(27);"G";
30 LPRINT "This line is BOLDFACE printing."
40 LPRINT CHR$(27);"E";

70 LPRINT "This line is EMPHASIZED printing."
80 LPRINT CHR$(27);"F";
90 LPRINT "This line is normal printing."
100 END
Run this program. The results will look like this:
This line is BOLDFACE printing.
This line is BOLDFACE and EMPHASIZED.
This line is EMPHASIZED printing.
This line is normal printing.
