Read carefully the documentation about the WRITE instruction - in the

you can specify the length of the data you write. If you don't specify
it, gambas will do it

The subroutine could look something like this:
sub square_diamond(left, right, top, bottom as integer)
step = (right+left) / 2
SORRY: step = (right - left) / 2
Urgh...

Hi,
May be I've to elaborate a little bit?
I see the process like this:
1) you transpose each cell of your initial array to a pixel
of a picture where the coordinates of the pixel is equal to
the coordinate of the cell and the grey color of the pixel
is equal to the elevation in the cell
2)

Simple problems
Hi,
I've just a crude idea and know nothing more on this subject!
If you assume that each value in your big array is a color
value instead of an integer, may be you can find some
graphic effect wich simulate your algorithm.
It seems to me that it's like to find an intermediate color
between 2
I need to create an 8 gigabyte binary file with zero values throughout it. Is
there a faster way to do this than to create a big string of zeros and write
it to the file multiple times? What I'm doing right now works but seems like
a really ugly method:
' Zero-out the file.
Zero = Chr$(0)

On Linux, If you seek and write past the real end of a file, then the file
is
automatically extended.
So the simplest is writing where you want in the file only when you need.
Just
don't do that randomly, to prevent the disk from seeking too much.

You only need create the file once, then copy it whenever you need to
during testing. If you really must create the file every time, let dd
do it by using Gambas' Exec
This is the absolute fastest way to do it.
