dont know if this it to much to do via a script but here goes
i have a file with 700 lines or so by 14 columns of data , in the 4th column
i have a list of numbers ,
what i am after is someway of when a change in the number in the 4th column
appears,select all the data above with the same number and either copy/cut
that data to a new file or even a new tab (naming that tab to the same as the
number) in the same file , then continue till the next change in column 4
and so on till the page is empty. so i end up with a file full of tabs for
each number change....

maybe its to much , thanks for trying in advance
