  put URL "file:temp.txt" into tData
  put empty into tDisplayData
  put 0 into tCounter
  repeat for each line L in tData
    put tCounter && L & cr after tDisplayData
    add 1 to tCounter
  end repeat
  put tDisplayData  into field "Field"

It may look clumsy to scan through each line like this - but Rev is very 
fast at doing that. This did my 6000 line, 1 Mb file in about 80 
millisecs - so you don't need to worry about speed.

You could also do it by some variation of   setting the vscroll of field 
1 to the thumbpos of field 2
but I just find it easier to do it this way.

You could also do it by putting the two fields into a group and 
scrolling the group (I think - haven't tried that way myself).

Happy New Year !!
