[Swift-user] Writing to an output file

[Michael Wilde]

Erin,

An app function can only be the declaration of a single external 
application. It can't be anything else - and here you're trying to use 
an app declaration to return a value, like a Java property.

You'll typically want to place statements like "int x = 10" in open code 
  (ie outside all otehr procedures, typically at the end of your script) 
or inside a compound procedure.

Next, what you're trying to do here doesnt fit well with the Swift 
model: you typically dont take data that you compute directly in Swift 
(as opposed to in a Swift app) and write that data to a file. Files are 
typically written only by app procedures - i.e., they contain the output 
of programs.

In this test, were you just trying to fill an array with scalar values
