creating custom table using Proc Report problem

Hi,

I have to make a tabular report, using proc Report, for the sample input
file below:

----------------------
x | y | n1 | n2 | c1
----------------------
A | 1 | 22 | .9 | m
B | 1 | 20 | .4 | n
C | 1 | 32 | .3 | mn
A | 2 | 11 | .5 | op
B | 2 | 5 | .7 | mo
C | 2 | 29 | .1 | on
----------------------

and desired output report should look like:


|| y = 1 || y = 2 ||
---------------------------------------------
x || n1 | n2 | c1 || n1 | n2 | c1 ||
-------------------------------------------------
A || 22 | .9 | m || 11 | .5 | op ||
B || 20 | .4 | n || 5 | .7 | mo ||
C || 32 | .3 | mn || 29 | .1 | on ||

That according proc report syntax: x should be a group variable, y should
be across, where as n1 & n2 are analysis while c1 is display (character).

If I specify column statement with c1 in it, proc Report gives error as it
allows grouping of numerical variables together, and does NOT include c1,
without a statistic.

The problem is how to group (n1, n2, c1) & place it under y?
