Further limits of GRASS

Thanks for the responses to my problem on reading raster data into GRASS.

One response mentioned having run out of space.

We've installed a new 2Gbyte disk, the DTM ASCII file is about 42Mbytes,
and there's >1Gbyte free space on it.

The only thought I've had is how is GRASS processing the file - as our
IPX only has 16Mbytes of RAM, I suppose it must be using virtual memory -
is this 'swop space'. If I do a 'df' the system shows '/' has about
7.5Mbytes, '/usr' has 38Mbytes (+ others). Is the 7.5 Mbytes the swop
space or is the 38 Mbtyes ?. If it is the 7.5 Mbytes, how can I increase
the space ?

Please write any responses in words of one syllable, as I've little
knowledge of UNIX - I know, it shows :sunglasses:

Thanks again in advance,
