case 2:
iterating through a cr-separated list and needing to modify lines
(note: this is even more extreme if I need to delete lines):
put tBreaks into tNewBreaks
put 1 into tLine
repeat for each line tBreak in tBreaks
put item 1 of tBreak into tID
put the long id of control id tID of the topstack into tObjectID
put tObjectID into item 1 of line tLine of tNewBreaks
add 1 to tLine
end repeat
return tNewBreaks
Is it really worth doing this by changing each of the lines ?
Is it not easier, clearer and very likely just as fast, to do:
put empty into tNewBreaks
repeat for each line tBreak in tBreaks
put item 1 of tBreak into tID
put the long id of control id tID of the topstack into tObjectID
put tObjectID & the itemDel & item 2 to -1 of tBreak &CR after
tNewBreaks
end repeat
return char 1 to -1 of tNewBreaks
With a bonus that deleting lines (i.e. not copying them) is easier.

Alex
