comparing data
 

Is there a macro or program that can be created so that I could lay
down a list of numbers and then in column 2 I want to copy a seond list
of numbers but I want those numbers to go in cells if it matches the
first cell. Lets say that the first cell is a master and I want to
constantly copy different sets of numbers into the following columns
and I want a program that will automatically dictate which cells the
numbers will go into based on the original column.
