This is news to me! Put this in a button script:

on mouseUp
   put getArray() into tArray
   combine tArray by cr and "="
   put tArray
end mouseUp

function getArray
   repeat with n = 1 to 10
     put "this is in an array" into tArray[n]
   end repeat
   return tArray
end getArray

This works perfectly on my machine - what happens on yours?

What you can't do is use a function that returns an array as a  
parameter to another handler:

get someFunction(getArray())

and you can't use an array in a "do" statement:

do "someCommand someArray"

Many (perhaps most) of my apps rely on functions that return arrays....

Best,

Mark
