Urgent: Importing floating point

[Cosyn Bart]

Hi,
I would like to import floating point files into grass. Using r.in.ascii 
gives a core dump. Probably due to the volume of the files! Therefor I 
would like to import the data by just creating the needed header! I made 
a dummy file in the cell dir and putted the fp images in fcell! I created 
f_format in the subdir of the file in cell_misc! No problem up to that stage!
BTW I gave -1 as the format in the header file!

BUT now I want to run
r.support! He gives an empty raster map? This looks normal BUT THAN!!!!

He gives a warning can not write f_range file !!!!!

Even doing a touch of f_range in the cell_misc he is still not able to 
write this file!

Here come the question!

1) Who imported already fp files in this way! Is there a similar way to 
import data

2)Is there a program to import binary fp data?

                Thanks Bart
