In the MICROLINE Standard emulation, the electronic Vertical Format Unit lets you program up
to 12 different sets of vertical tabs. You can load a maximum of 54 tab stops into one set of
channels. The command DC4 SP...SP n ... SP...SP ? is used to set up the tabs. Then whenever
the printer receives a VT code followed by a channel code, it will skip to the next tab stop in
that channel.
To load in your selected tabs, follow the DC4 code with one SP code (decimal 32) for each line
to be skipped to advance down the point where you want the first tab stop. For example, to
advance down three lines, use DC4 SP SP SP. Then enter the value you wish to assign for the
channel code n, taken from the table below. Next add more SP codes equal to the number of
lines to be skipped down to the next tab stop, followed by the next channel code value.
Continue this process until you've entered all the stops you want (up to a maximum of 12) for
that channel. Add enough spaces at the end of the sequence so that the number of spaces in
the sequence equals the number of lines on your page. Follow this with the ? character
(decimal 63).
Once you've set up the channels, send the VT n command to execute a vertical tab to the next
stop in the channel code sequence specified by n.

The skip down command makes it easy to move rapidly down a page. This is a useful feature
when you are creating headings or filling in forms. The variables H
