Now, let’s set some vertical tabs of our own. Add these lines to the program:
20LPRINT CHR$(27) ; “B”; CHR$( 10) ;CHR.(15)$ ;
30[.F’IllNT W/$ (25) ;(:liR$(30 ) ;ClIR$(0 ) ;
(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.
[::(:j{,j~rpl ‘r~~ .
Add one more line to the program to demonstrate one more feature of vertical tabs.
