nOne-time horizontal tabs

Suppose you need to move to a position across the page, but you only need to do it once. It doesn’t make much sense to set up a tab to use only one time. There is an easier way.

The solution is called a one-time tab. Table 5-8 show the three commands.

Table 5-8

One-time horzontal tabs

Function			Control code
One-time horizontal tab of n			(ESC) “f” 0 CHR$(n)
spaces
Absolute	horizontal	tab	(ESC) “$” CHR$(nl) CHR$(nZ)
			(ESC) “\” CHR$(nl) CHR$(nZ)
Relative	horizontal	tab	(except IBM-P mode)
			(FS) “\” CHR$(nl) CHR$(azZ)

(IBM-P mode)

The first command in Table 5-8 moves the print head n col- umns to the right. It has the same effect as sending n spaces to the printer.

The absolute horizontal tab command moves the print head to a specified position on the page. The position that you want the print head to move to (measured from the left margin) is specified by the values of nl and n2 in 1/604nch units using the formula nl + n2 x 256.

Try this program to see how this works.
