If a skip command is entered without further vertical tab positions
being set, a line feed is executed.
Function
Select vertical
tabulator channel
Load vertical format
You can set up to eight separate vertical tabulator groups - also cal-
led channels. The corresponding command ESC b has the same for-
mat as ESC B. Tab positions must be defined in ascending order and
ended with NUL. You must also define for which channel tabs are
to be set, by inserting a value between 0 and 7 for the variable n.
After setting the desired tabs in the respective channel being used
you can move to a vertical tab by specifying a channel with ESC /
and then sending a VT command.
Example:
The following BASIC program sets tabs in three channels and then
jumps to several vertical tabs in the various channels:
10 REM Vertical tabulator channel
20 REM tabulator stop in channel 0: line 10,
20, 30, 40, 50
30 LPRINT CHR$(27); "b"; CHR$(0); CHR$(10);
CHR$(20); CHR$(30); CHR$(40); CHR$(50);
CHR$(0)
40 REM tabulator stop in channel 1: line 5, 15,
35, 45, 55
50 LPRINT CHR$(27); "b"; CHR$(1); CHR$(5);
CHR$(15); CHR$(35); CHR$(45); CHR$(55);
CHR$(0)
60 REM tabulator stop in channel 2: line 12,
