a regular expression question, or at least a text manipulation question

[Jim Ault]

Just thinking, and here is a bit more compact code to do the job:
It should run about the same speed.

>   repeat for each line LNN in incomingList
>     put word 1 of LNN & cr after prefixList
>   end repeat
>   
>   split prefixList using cr and tab
>   put the keys of prefixList into prefixList

could be replaced by the three-liner

  get incomingList
  split it using cr and space
  put the keys of it into prefixList
