Thanks so much for your response. I am having some troubles with it though.
I have posted my efforts on to a web site to avoid copying large amounts of
code into the message - it's not very long but I thought it would be
cleaner.

http://www.tompagenet.co.uk/fits.php

there are links on the right to my original code (as hinted at in my first
post) and the code that I created after your suggestions. The new code fails
to run, almost certainly because of the:

fits_write_img(fptr, TDOUBLE, fpixel, nelements, array[0][0], &status)

line in the code. This calls an external procedure (one of the CFITSIO
procedures - http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html
for those who are interested).

The trouble is that this appears to expect an array of the form array[0][0]
(which is two dimensional, but then it knows it is three dimensional and
works out the third dimension by using the nelements argument which explains
the total number of elements and thus if you know two dimensions it can
calculate the third.

Should it be of importance, these are the argements both procedures take:
* wldepth - the size of the dynamic array dimension (the other two are of
static size griddef)
* inarray[][griddef][griddef] - the inputed array (basically the data to
write out by the procedure seen above)
* line - a number that simply alters the filename (irrelevant)
* type - ditto (irrelevant)

Thanks for any help with this, it is very much appreciated!

Thanks, Tom
