Caution when counting words, items, lines in xtalk.
Using either "the number of lines in"
or "for each" can give unexpected results.

If the last character in a field is a return, the last line is empty and
DOES NOT COUNT.  The same for ("," items) and (" " words)

Using "& null" will work for words/items/lines
and give you what you would want in most cases.
See below.

Paste the following into a new mainstack stack script, dblclk and study the
difference.

on mouseDoubleUp
  put "one,two,three,four," into txtList --note last comma
  replace "," with cr in txtList
  
  -------- usual 2 methods ...oops
  repeat with x = 1 to the number of lines in txtList
    put "x is " & x into line x of withXresult
  end repeat

  repeat for each line LNN in txtList
    put "money" & cr after forEachResult
  end repeat
  
------- Ahh, more like what we naturally think
  repeat with x = 1 to the number of lines in (txtList & null)
    put "x is " & x into line x of withXnullResult
  end repeat
  
repeat for each line LNN in (txtList & null)
    put "money" & cr after forEachNullResult
  end repeat
-------------------
breakpoint
--note the resultant variables in variable watcher

--withXresult = 4 lines
--forEachResult = 4 lines

--withXnullResult = 5 lines
--forEachNullResult = 5 lines & more money

--basically, if the last word/item/line is empty it does not count
--adding null forces it to count

end mouseDoubleUp
---end copy -------------------------------
