writting an array to a text file

[Guest_imported]

How do i write an array of, for example, 30 integer values to a text file? I need to print these values to a file for storage purposes so they can be referred to in the future. Once they have been written to the file I will empty it and calculate another set of values and store them. This process repeats for about 20 iterations.

Thanks
John

//The following code just loads an array with random
