Dear IDL users:

I would be grateful if someone could guide me:
I have five text files each of 7 columns by 9 rows
file_one = 'C:\one.txt'
file_two = 'C:\two.txt'
. . .
file_five = 'C:\five.txt'

How can I calculate the mean of first row for each file, if mean of first column of each file is 50?
I would appreciate a very simple code to be learn.
Keira
