The .linestart statement changes the position of the current marker for the output line so that the next text printed by the .print statement appears at the current left margin. The left margin is set either by the .lm statement, by default, or by the left edge of the column currently in use while in a .within block. The .linestart statement is useful in reports that use the .tab statement extensively. The .linestart statement always restores the current position marker to a known position, at the beginning of the line.
