Subject:      Re: mean value

I'm not sure what you mean with "overlaped" tables and I don't know what's
the mean-value between two tables...

However: tables of the same structure you can concatenate with SET:

data both;
  set first
      second;
run;

or with proc append:

proc append base=first new=second;
run;

then you can calculate MEAN statistic on one or more numeric variables:

proc summary data=both nway;
  class var1 var2 ; /* if you have a classification, otherwise omit */
  var num1 num2 num3; /* the numerics */
  output out=result
         mean=;
run;

you get all the means of each group in the same names like the originals.

Is that what you need?
