Handling Long ID in Params?

Thanks Ken, you got me on the right path.  I lost so many hours on this dumb
thing, but I think it's a valid concept worth using.

Again, the idea is to be able to execute any private command of a script
using a single "router" command, with any number of parameters.  The caveat,
as Ken pointed out, is that long object ids need to include "long id of"
when used as parameters.  The code is simplified below:

command runPrivateCommand pCommand
   put item 2 to -1 of (word 2 to -1 of the params) into commandParams
   repeat for each item theString in commandParams
     -- strip outer quotes of params
     put char 2 to -2 of theString & comma after theArgs
   end repeat
   delete last char of theArgs -- strip trailing comma
   do pCommand && theArgs
end runPrivateCommand

So, as a simple example, if a script has a private command:

private command getObjectID pObj
   answer the id of pObj
end getObjectID

...this command can be triggered by any external object via the above router
command (in the same script) with something like this:

runPrivateCommand "getObjectID","long id of" && long id of btn 1



Thanks again Ken.
