REFORM() will solve this:
IDL> a=indgen(2,3,4)
IDL> print, a[*,0,0]
0 1
IDL> print, a[0,*,0]
0
2
4
IDL> print, a[0,0,*]
0
6
12
18
IDL> print, reform(a[0,0,*], 1,4)
0
6
12
18

Hi David
Thanks for the reply, no it was all done on a PC. I get the same
problem using the print command: the data in the z dimension has
spaces. And no I haven't used a format statement.
all the best
Steven

Did you create this file on a PC and open it on a UNIX
machine? If so, I would try running dos2unix on it. This
looks more like a file transfer problem to me, than a file
writting problem. Did you use some kind of format statement?
Cheers,
David
