PROGRAMMING
Run
the program and compare:
Notice
that the angle
is
steeper and the
two
lines are closer together.
This
is
because each individual
column
now
overlaps the next one.
Notice also that
it
prints more
slowly,
although
with
this
amount
of
printing
the difference in speed may be hard to detect.
Now
try
double
density, normal speed
(ESC
V):
30 LPRINT CHR$(27);CHR$(89);CHR$(11);CHR$(0);CHR$(1);CH R$(2);
CH
R$(4);CH R$(9);CH R$(18);CH R$(36);CH R$(72);CH R$(144);CH R$(32);
CH
R$(64);CH R$(128)
Aside from printing speed, there should be no difference, because
the pattern does not include adjacent dots;
if
it had, some dots
would
have been skipped.
