line feed, which means that the subsequent movement of the print head will be from the left margin to the right. To see this in action, delete line 10 and change line 40 to read:

40 FOR X=1 TO 10: LPRINT CHR$(27)"<"CHR$(124):
NEXT X

When you RUN it, you can watch the print head move to its leftmost position after it prints each line.

Unidirectional print motion straightens out the slight misalignment of characters that results from printing bidirectionally in the Elite or Compressed Mode. The difference is subtle, but often it’s such subtleties that make a topnotch graphics display possible.

International Characters

Remember the tilde that you used at the beginning of this chapter to create the approximately equal sign? Well, that tilde is only one of the many uncommon characters that are stored in the FX as components of the nine international character sets.

We mentioned the international character sets in Chapter 1, when we explained that the factory-set defaults for the DIP switches include the selection of the USA character set. Besides the pound sign (#), dollar sign ($), and at sign (@), the USA set includes the nine other symbols shown in Table 6-1;one or more of these nine may not appear on your computer’s keyboard.
