Clear Horizontal Tabs
Clears all horizontal tab stops. It is merely a variant behavior of the Set
Horizontal Tabs function, where the NUL acts as an early terminating
character, as existing tabs normally clear before setting any new tabs.
Perform Vertical Tab
Prints the contents of the current print buffer, and then moves the print
position 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
currently selected line spacing, without changing the carriage position.
Set Vertical Tabs
Resets the current tabs, and vertical tabs are set up, based on the current
line spacing. Tab settings are not affected by subsequent changes in line
spacing.
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.
