Again the FAQ is worth reading, I can't see what you've typed nor what
error messages you are getting returned, "still does not work" is not
very informative when it comes to trying to work out whats going

Please copy and paste (in a post to the list!) the results from what
you're typing.

As noted above, I can't see that message!  By the sounds of it you
only need to bother setting the memory.

The first step in assessing how much memory you require is to work out
how "large" your data set is.  You're -insheet-ing the file, so how
many Mb is the file in question?

The next step is to determine if your hardware has sufficient RAM to
handle this.  You've given no indication as to the operating system
your using but under *NIX systems typing 'free -m' in a terminal will
show how much RAM you have, and under M$ variants you can get to this
under the information provided when you right-click on "My Computer"
and select "Properties"

Once you've assessed that you have sufficient RAM to cope with your
data you need to then -set memory XXM- thats it, no need to worry
about -set maxvar- or -set matsize- (at least at the time being).

You'll probably find the following FAQs useful too....
