If your system passes the codes directly to the printer without changing them, you will get a printout like Figure 2-3.

Most BASICS, however, are not quite that straightforward. For example, the IBM-PC prints the following.

Figure 2-a. Sample hexadecimal dump with IBM-PC

When the IBM-PC BASIC interpreter sends hex code OD (carriage re-

turn) it adds an extra hex OA (line feed). Hex code 1A (end-of-file) also gets -

special treatment: the interpreter does not send it at all. This can cause problems in programs that generate graphics or download character data, but there is a solution. Try changing line 20 in the preceding program and adding the coding shown below.

Coding for IBM-PC with monochrome display:

20 GOSUB 100

100 O=INP(&H3BD):IF 0<128 THEN 100

110 OUT &H3BC,I :OUT &H3BE,5 :OUT &H3BE,4

120 RETURN
