How can I pass a handler a long ID as a string?

[Geoff Canyon]

I've hit this before. I generally postfix a cr like so:

   put (the long id of fld "myField" of cd "myCard" of stack  
"myStack") & cr into tParam
   myHandler tParam

Then in myHandler:

on myHandler pID
   delete char -1 of pID -- ready to go now

or if it could be a list:

on myHandler pIDList
   repeat for each line tID in pIDList
