IBM 4400 Set Relative Horizontal Print Position in n/120 Inch, Set Vertical Tabs in Channels

Set Relative Horizontal Print Position in n/120 Inch

Set Relative Horizontal Print Position in n/120 Inch

ASCII Code ESC \ n1 n2

Hex Code	1B 5C n1 n2
Dec Code	27 92 n1 n2
Purpose	Moves the logical print head to a relative horizontal print
	position, using 1/120 inch increments.
Comment	Adds (n1 + 256n2)/120 inches to the horizontal position of the
	logical print head. The number sent is two's complement, with
	negative numbers moving to the left. The command is ignored if
	it would move the logical print head beyond the page margins.

Set Vertical Tabs in Channels

ASCII Code ESC b c n1 n2 n3 ... nk NUL

Hex Code 1B 62 c n1 n2 n3 ... nk 00

Dec Code 27 98 c n1 n2 n3 ... nk 0

Purpose Assigns vertical tabs to channels selected by ESC / (see page 187).

where: c = 0 through 7 n = 0 through 255

n1 through nk specify the line number for the vertical tab(s), up to a maximum of 16 tab positions. NUL must end the sequence.

Comment Channels are selected by ESC /. The distance of each tab stop from TOF is the current line spacing times the number of lines given in n.

If paper movement is commanded to a value of n greater than the page length, the paper movement command is ignored. The values of n must be in ascending order. If they are not, the sequence up to and including the out of sequence number is ignored. The rest of the load is processed. Skip over perforation is ignored.

You can clear any channel by sending ESC b c NUL, where c is the channel number.
