Thanx for the help Alex the code worked great, I just changed the line;
put tCounter && L & cr after tDisplayData -- shows line numbers and data in field.
put tCounter & cr after tDisplayData -- shows only line numbers.
and thanx to Ken Ray & Wilhelm Sanke for the following line!!
set the scroll of fld 1 to the scroll of me
It's often the simplest code that gets the job done!
Cheers and thanx again...Dwayne.R

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
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 !!
