Example:
Suppose you want to print 400 columns
of
graphics:
-
n2=
1
-
256 ) 400
-
256
-
n1
= 144
-
If you
want
to print in single density graphics mode, the beginning
of
your statement should look like this:
-
-
-
-
IBM BASIC includes
two
functions that make calculating
n1
and
n2
-
very
easy:
•
MOD
divides
two
numbers and returns the integer remainder,
-
•
FIX
removes the fractional portion
of
a numeric expression
without
rounding it off.
See
your BASIC Manual for details.
Using these functions, you
can
express our sample numbers this
-
way:
O'!NDOTS=400
-
l T
$~~~~;C~~(7~Jfi::H~~DO~~
~:JP
··CHR$(FIX(NlQOTS/256»
-
IMPORTANT NOTE:
The
number
of
dot columns expressed by
n1
and n2 cannot be greater
-
than the maximum number
of
dot columns per line allowed for the graphics mode you are
using
(see
table below).
