Purpose

Sets up to 32 horizontal tab positions.

Expression

CHR$(27);

D

;CHR$(n1);...CHR$(n32);CHR$(0);

where

n1 through n32 specify the character column of the tab positions. CHR$(0) is the
sequence terminator.

Comment

You can set up to 32 different tab positions. The values must be listed in ascending
order or they are ignored. The physical tab position is the product of “n” and the
current cell width (1/pitch), excluding double wide. Tabs in excess of 32 or those
positioned beyond 13.2 inches are also ignored.

Clear the tab positions by sending the CHR$(27);“D”;CHR$(0) sequence. Power-
ing the printer on/off initializes the tabs to every eighth character column. Horizon-
tal tabs are accessed by control code HT.

Example

The following example illustrates horizontal tab setting and accessing.
