When you run this program, it looks like nothing happens. That’s OK. We’ll see why in just a moment. Save this program. We’ll need it again shortly.

PRINTING DOWNLOAD CHARACTERS

You’ve now defined and sent three characters to SR-10/15. But how do you know that? If you try printing those characters now (type LPRINT CHR$( 160) CHR$( 161) CHR$( 162)) you don’t get a flask, car and gun. Instead you get... J \ L or a%. That’s because the download characters are stored in a different part of SR-10/15’s memory. To tell it to look in download character RAM instead of standard character ROM it requires another command:

(For STAR mode)

<ESC> "$" n

(For IBM mode)

<ESC> “%” n 8

This command is used to select the download character set (if n= 1) or to select the standard character set (if n.=O). Let’s try it out. Enter this command:

LPRINT CHR$(27) "$1" CHR$(l60) CHRS(161) CHR$(162)
