Yes Rob, that is a problem, so if you have a closer look at my script 
:-) you'll see that I use the contents of the original control variable 
to build a completely new variable to avoid this problem. In my script 
(which I have inserted below) "variable" is the name of the original 
variable used for the control loop. The contents of it, with something 
else is a line is empty, are used to build up "newVariable". The 
original "variable" is never changed at all. Your solution does things 
the other way around but both are valid ways around the potential 
problem with "repeat for each" loops. BTW as this is purely a 
demonstrator script, it has no way of actually getting any data in or 
out - I leave that up to the individual user :-)

on newAddNew
   put empty into newVariable
   repeat for each line L in variable
     if L is empty then
       -- insert the new data in place of the empty line
       put newData & cr after newVariable
     else
       put L & cr after newVariable
     end if
   end repeat
   delete last line of newVariable  -- extra cr
end newAddNew
