I have a number of files with data that is presented like this (only much larger). 
1 G
2 F
4 H
8 T

[download]
5 Y  
6 R  
7 E  
8 I

[download]
2 H
4 T
3 G
8 R

[download]
I would like to create a new file containing all the information in these files and format it as follows. 
1 G  5 Y  2 H
2 F  6 R  4 T
4 H  7 E  3 G
8 T  8 I  8 R

[download]
Could someone please give me a few pointers as to how to do this? I guess I could open all the files, store them in separate hashes and then print them out somehow? Thanks in advance
