Browser, as always thanks for the help. All I need to do is have them outputted in the right positions so need need for the sort. However since I will be distributing this via pp as an exe I can't count on launching a separate process in the manner you described.

What I've done which seems to be working ok is pushing the data into a shared array (using locks to ensure that the variable doesn't get corrupted)

However since I'm not operating on the array until the end of my program it gets quite large.

I've been thinking about a solution over my morning coffe and here is my thought:

Push the data gotten in RetrieveInfo into a shared and locked array.
Then before the while loop in GetHml begins another iteration, check the size of array and if $arraysize >= $Arbitrary_value,
lock the array and call output() which will write the contents of the array and then flush it's contents.

What do you think?
