array: why does this not work?

[Ken Ray]

Oliver,

It's because your incoming variable can't be immediately resolved as an
array. You need to use "do" to put it togethre before returning the result:

local myArray

on mouseUp
  put 100 into myArray["test"]
  answer getArray("myArray","test")
end mouseUp

function getArray pArray,pKey
  do "put " & pArray & "[" & pKey & "] into temp"
  return temp
end getArray


Note the "local myArray" - in order for the "getArray" function to "know"
about the myArray array, it needs to be available to it either as a declared
"script local" or global variable.

Hope this helps,
