9 Vertical tabs
Vertical tabs have the same kinds of uses that horizontal tabs
do – they just work in the other direction. Horizontal tabs allow
you to reach a specific column on the page no matter where you
start from. Vertical tabs are the same. If you have a vertical tab
set at line 20, a vetiical tab (or (VT)) will move you to line 20
whether you start from line 5 or line 19.
-Vertical tabs are not set at the power-on default. If you send a
CHR$(l 1)which is the ASCII code for (VT) before we have set
up tabs, the command advances the paper only one line. Enter
this program to see how this works.
