Perform Vertical Tab
The contents of the current print buffer are printed first, then the print
position is moved to the next vertical tab stop. If no channel is selected,
then channel 0 is used. The carriage position is changed to the start of the
next print line. If the vertical tab is performed beyond the last tab position
set or beyond the last line of a form, then a form feed is performed
.
If no
vertical tabs are defined, then the paper advances one line, using the cur-
rently selected line spacing, without changing the carriage position.

Set Vertical Tabs
The current tabs are reset, and vertical tabs are set up, based on the current
line spacing. Tab settings are not affected by subsequent changes in line
spacing.

where n1 is the first tab (range of values for tab stops: 1–255), n2 is the
second tab (all tabs must be in ascending order) , ... are subsequent tabs
(maximum number of tabs: 16), nk is the last tab to set (any value less
than the previous tab value acts as a terminating character), NUL is the
terminating character. All tab settings with this function are stored in
channel 0.
Clear Vertical Tabs
All vertical tab stops are cleared. It is merely a variant behavior of the Set
Vertical Tabs function, where the NUL acts as an early terminating charac-
ter, since the function normally clears the existing tabs before setting any
new tabs.

it stores the tabs into a specified channel, as specified by the variable c .
