Nope. The 'startup' message is the only message MC sends/fires in a CGI script (I think), but it's just another Metatalk message and follows all the same rules as all the others (no nested handlers). From within the 'startup' handler, you can reference any number of other standard or custom handlers/functions/etc. Like this:

-- start of script --

on startup
  if firstchar(the platform) = char 1 of the systemVersion then
    doDance "Windows?"
  else
    doDance "Mac?"
  end if

  writeSomething
end startup

function firstChar pCharString
  return char 1 of pCharString
end firstChar

on doDance pDanceType
  tellSomeone "Are you running" && pDanceType
end doDance

on tellSomeone pMessage
  put "Content Type: text/html" & cr \
  & "Content Length:" && length(pMessage) & cr & cr

  put pMessage
end tellSomeone

on writeSomething
  put "Uhhhhh...."
end writeSomething

-- end of script --

The 'startup' message has no params, but you can create other handlers in your CGI script that use'em (see above).
