Chapter 2 Program Instructions
Examples You can check what characters the host produces by means of a simple
program. Pressing different keys should produce the corresponding characters
both on the label and on the screen of the host. Else, try another character
set (see NASC). In this example we presume that the keyboard produces
ASCII 81 dec. and ASCII 90 dec. when you press the Q and Z keys
respectively. Should any unexpected characters be printed on the labels or
the screen, check the manuals of the host computer or terminal for information
on what ASCII values will be produced by the various keys and how the
screen will present various ASCII values received from the printer.

40 PRTXT A$
50 PRINTFEED
By adding a MAP statement in line 5, you can test what happens. In this case
we re-map the character Q to be printed as Z, as in the explanation on the
previous page. After printing, we map the character Q back as before.

60 MAP 81,81
A device connected to "uart2:" produces strings always starting with the
control character STX (ASCII 2 decimal). STX can be filtered out by mapping
it as NULL (ASCII 0 decimal):
10 MAP 2,2,0
Should "uart2:" be appointed standard IN channel (see SETSTDIO), the first
parameter can be omitted from the example above:
