Ok, that's right, but if I write i.e.
openw, ostream, 'matrix.dat', /width=500
I always receive a syntax error ?!?!?
Jesus, IDL makes life really hard.

You could not be experienceing the following problem?
IDL> print,150*441
614

In that case, you need to work "long", namely do something like
IDL> print,150L*441
66150
or more verbose
IDL> print,long(150)*441
66150

IDL uses 80 column widths by default. If you would like some
other width, use the WIDTH keyword when you open the file
for writing.

No.

Pity.
