In this program we set tabs at 10 and 20 in channel 1 in line
20. In line 30 we set tabs 15 and 25 in channel 2, and in line 40
we set tabs 17 and 28 in channel 3.
Because the channels are stored, you must make the printer to
recall one before you use it, so we used (ESC) “/” CHR$(nU) in
line 80.
CENTERING AND ALIGNING TEXT
Text can be arranged in any of three formats: left aligned or
left-justified (normal printing with “ragged” right margin),
centered between the margins, or right aligned (right-justified).
These are selected by the following commands:
Table 4-11

Left-justified printing (ESC) “a” CHR$(O)
Centered printing (ESC) “a” CHR$(l)
Right-justified printing (ESC) “a” CHR$(2)
