Hi Viktoras,

Richard gave you great advice if you're looking to
save your index as a stack ; but now I'll try and
explain how you can do it with every-day text files
and the 'combine' and 'split' commands.
I've assumed that you don't have a 'tab' character in
your text.

## Saving the array to a text file
  combine tIndexArray using return and tab
  put tIndexArray into URL("file:" & tFilePath)

## Loading the array from a text file
  put URL("file:" & tFilePath) into tIndexArray
  split tIndexArray using return and tab

Hope this helped,

Jan Schenkel.
