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.

This is a useful feature when you are creating headings or filling in forms. The variables Hn Ln represent a 2-digit ASCII number from 00 to 99 which allows you to skip up to 99 lines; a value of 00 for Hn Ln in the command results in no line feed.
