Here is an example of a simple script I use for a stub-download-Main
 with output to follow:
--field 2 log
--field 3 pct
------------------------------------
on mouseup

 libURLSetLogField "field 2"
 libURLSetStatusCallback  "setPercentage",(the long id of this card)
    --bunches of other stuff
end mouseup


on setPercentage urlDL, statusDL
  replace "/" with space in urlDL
  if statusDL contains "loading" then
    try
      put 100*item 2 of statusDL/item 3 of statusDL into pctDL
    end try
    put  word -1 of urlDL &"  %done......  "& pctDL & cr before field 3
  else if statusDL contains "error" then
    --to be done later
  else
    put cr & "status of "& word -1 of urlDL & " is ... "& statusDL & cr
before field 3
  end if
end setPercentage
