question about find and replace

[Mark Schonewille]

Hi Peter,

Here's a possibility. Perhaps someone can come up with a shorter  
version.

constant dot = "."

function formatDottedNumbers
   set the numberformat to "000"
   set the itemDel to dot
   repeat for each line myLine in myData
     put dot & item 2 of myLine * 1 & dot & cr after myNewData
   end repeat
   return char 1 to -2 of myNewData
end formatDottedNumbers

I believe regex is great to find data, but you can't use it to find  
and edit all instances of a search pattern, if all new values have to  
be different.
