Forcing a variable to evaluate as an object reference

[Jim Ault]

Further note about using FOR EACH
when doing multiple repeat loops *in the same handler*, do not use the same
temp variable name.  I have found reusing the tempVar name is unreliable.

Note the LNN and LNN2

set the itemdel to tab
repeat for each line LNN in listRed
   --no -- delete item 1 of LNN
   --no -- then try to use modified LNN for some purpose
   put item 2 to -1 of LNN & cr after newListRed
end repeat
delete last char of newListRed
put newListRed into listRed

repeat for each line LNN2 in listGreen
   put "done" & tab & LNN2 & cr after newListGreen
end repeat
delete last char of newList Green
put newListRed into list Green
end repeat
