OK - you guys have hit what I need 100% on target.

What I have to output is:
location,login1,login2,login3 location2,login1,login2,login3,login4, ...

If my data structure is: $table = {
'West' => [login1,login2,login3],
'East' => [login1,login2,login3],
'North' => [login1,login2,login3,login4],
'South' => [login1,login2,login3]
}

Then how do I iterate through to get the data into:
West,login1,login2,login3 East,login1,login2,login3 ...
