Add one more line to the program to demonstrate
one more
feature of vertical tabs.
80 LPRINT CHR$(ll):"FIFTH TAB."
Now when you run the program the first page looks just like
before, but line 80 sends one more <VT > than there are tabs.
This doesn't confuse your printer - it advances the paper to the
next tab position which happens to be the first tab position on
the next page. That's nice, isn't it?
There's a one-time vertical tab command that works just like
the one-time horizontal
tab command.
Try this program
how
these command work.
10 ' Demo of print
positions
20 LPRINT w* 1st Line, 1st Column"
30 LPRINT CHR$(27);"fl";CHR$(S);
40 LPRINT w* 4th Line, 1st Column"
50 LPRINT CHR$(27);"fO";CHR$(7);
60 LPRINT '** 5th Line, 7th Column"
70 LPRINT CHR$(27);"fl";CHR$(3);
80 LPRINT CHR$(27);"fO*';CHR$(5);
90 LPRINT ))* 8th Line, 5th Column"
100 END
In this program,
line 30 sends a one-time vertical tab with
(ESC) "f" 1 command.
Line 50 sends a one-time horizontal tab
with (ESC) "f" 0 command.
Finally, line 70 and line 80 send
one-time vertical tab and one-time horizontal tab, so the line 90
prints text at the specified position.
