Vertical Tab Set (Serial Matrix)
P-SERIES
ASCII Code:
N/A
Hex Code:
N/A
Purpose:
Sets vertical tab positions.
Expression:
CHR$(27);"B";CHRS(n);...CHR$(nk);CHR$(0);
where:
n1 through nk specify the line number for the vertical tab(s),
for a maximum of 16 tab positions. CHR$(0) is the sequence terminator.
Comment:
The physical position on the paper is the product of n" and the current line
spacing. Subsequent line spacing changes do not change the tab position. If
the value of n" defines a tab stop that exceeds the forms length, that tab posi
tion is ignored.
In the Serial Matrix mode, vertical tab positions are set by control code ESC B
and executed by control code VT. The tab positions must be in ascending or
der or the sequence will terminate. More information regarding Serial Matrix
vertical tab setting is provided in the Vertical Format Units chapter.
