Ah, I assumed you didn't need to read from the process. If you don't need to
read or know when it's done then:
open process appPath&" "&srcPath&" "&trgPath for neither
If you need to know when it's done then something like this should do it
(untested hacking in email client)
put appPath&" "&srcPath&" "&trgPath into tProcess
open process tProcess for read
send "ReadProcess tProcess" to me in 0 milliseconds
on ReadProcess pProcess
local tOut
repeat
read from process pProcess in 5 milliseconds
put it after tOut
wait 20 milliseconds with messages
if the result is "eof" then
close process pProcess
exit repeat
end if
end repeat
PDFExported tOut
end ReadProcess
on PDFExported pOutput
-- let the user know
end PDFExported
