I don't know if this will be faster, slower, or what !?! Something like ....

   put myVar into tCopy
   replace CR with TAB in tCopy

   put itemoffset("incertain", tCopy) into tmp
   put the number of chars in item 1 to (tmp-1) of tCopy into tCharCount
   put the number of items in char 1 to tCharCount of myVar into 

Or, depending on what you do next, just go on using charOffset rather 
than itemOffset for the following code.
