I'm not exactly sure what you are asking in terms of output.

You want to import 90 lines, strip off the first two fields separated by a 'tab' character, join the last two with a '/', push them onto an array, print the first field, print the whole array, then cycle back for the next 90?

Or do you want to build 301 X/X columns side by side? Something like this:

000217
N/N
G/G
A/A
A/G
A/A
A/G
A/A
A/G
A/G
(until 90 items are listed),

Then cycle back and grab another 90, and add to the above by adding another column onto the X/X list?

Let me know. I'm kind of unsure about what you are asking.
