set at line 20, a vertical tab (or <VT>) will move you to line 20 whether you start from line 5 or line 19.

The vertical tab is not set at the power-on default. If you send a CHR$(ll), which is the ASCII code for < VT > , before we have set up tabs advance the paper one line. Enter this program to see how this works.

40LPRINT CHR$(11) ;“FIRST TAB.”

50LPRINT CHR$(ll);“SECOND TAB.”

60LPRINT CHR$(11) ; “THIRD TAB. *’

70LPRINT CHR$(ll);“FOURTH TAB.”

Now, let’s set some vertical tabs of our own. Add these lines to the program:

20LPRINT CHR$(27);“B”;CHR$(lO);CHR$(15);

30LPRINT CHR$(25);CHR$(30);CHR$(O);

(ESC)“B” is the command to set vertical tabs. Like the horizontal tab setting command, tab positions must be defined in ascending order. Our example sets vertical tabs at lines 10, 15,25 and 30. Then the CHR$(ll) in each of the following lines advances the paper to the next vertical tab. The printout is shown below.

FIRST TAB.

SECOND TAB.

THIRD TAB.

FOURTH TAB.
