You can optionally declare variables locally if you prefer; you can enforce
this by setting the explicitVariables property to true.
Good practice? It does require more discipline and a little extra typing,
but can help debugging. It has no effect one way or another on performance.
I think this one may be considered a matter of taste.

You can replace:
repeat for each line thisLine in theFileList
if char -3 to -1 of thisLine is "txt" then put thisLine & \
return after theList
filter theList with "*.txt"
