If so, this happened because the cursor is automatically moved one space to the
right after any character is printed. To enter characters vertically, the cursor must
be repositioned both vertically and horizontally to compensate for the automatic
cu rsor movement to the rig ht.
To print the verticalline of the square, then, repeat the sequence of CURSOR
DOWN

CURSOR LEFT

and RIGHT L1NE VERTICAL

Do this five
times, and vou should have printed the right side of the square (Figure 5-3el.
Step 6: Type the bottom right corner of the square using the BOTTOM

vou haven't already done so, use CURSOR DOWN

and CURSOR

[9
to position the cursor at the corner of the square; th en press the cor-
ner key (Figure 5-30.
Step 7: Draw the bottom line. Because we are using COR NE R keys, we
need just five BOTTOM L1NE HORIZONTAL

(Figure 5-3g).
One method is to enter the line from right to left. After each character entry
on the bottom line, two CURSOR LEFT [9 movements will be needed to correctly
position the cursor for the next entry.

A second, and possibly more naturaL method of drawing the bottom line is
from left to right. To do this, position the cursor to the leftmost space of the bot-
tom line (one space to the right of the left edge of the screen); this can be done
using six CURSOR LEFT 19 . You can then easily enter five BOnOM L1NE
HORIZONTAL
0
to create the bottom line of the square.
