Dear Tomson

print,a_not_b(a,n)
% Compiled module: A_NOT_B.
% Compiled module: UNIQ.
0 1 2 4 5 7 8 9

You can get a_not_b and several others from our library.

http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/a_not_b_dbase.pro.html

There is an a_and_b routine and some others available.

Some people asked how to unpack tgz files. So here is an explaination what
it is. The tgz extension is named tarball and it is the same as tar.gz.

You can unpack it on MS windows by winzip or on unix by gnu tar with tar
zxvf file.tgz.

regards
Reimar
