Hyperpeople!  I am looking for an external that can set the file and
creator attributes of a file.  I have tried using  Larry Wolfarth's 
"ChangeFileType" xfcn from the "Developer Stack v.1.3", but am having 
trouble getting it to work from within a script.

This works when typed into the message box:

ChangeFileType("HD40:TempFolder:foo.txt", TEXT, ALFA)

"NoError: File TYPE/Creator changed" is put into the message box,
and the file type and creator are properly set.

If the same thing is put into a button script:

on mouseUp
  ChangeFileType("HD40:TempFolder:foo.txt", TEXT, ALFA)
end mouseUp

the script fails with "Expected ")" but found ",".

What am I doing wrong?  Is there another external that will do the job?
I am trying to create a stack that will do batch operations on text
files -- everything else works except this!

If the topic is of interest to others, I'll summarize.
