[Swift-devel] unitialized error when swift app returning a non-file type

[Ketan Maheshwari]

Hi,

Wondering if this is an expected behavior. I intend a Swift app to return a
variable which I then receive in a Swift variable. This variable is
uninitialized since initializing it would close it out.

Here is a minuscule example:

app (string b) s_app(string a){
 str_app a b;
}

string[] b;

foreach i in [0:10]{
   b[i]= s_app("hello");
}

The s_app links to a bash script as follows:

#!/bin/bash

$2=$1

On running this:

$ swift str.swift -tc.file tc -sites.file sites.xml
Could not start execution
Uninitalized variable: b


The detailed exception from the log is:
2013-04-01 15:47:33,755-0500 DEBUG Loader Detailed exception:

Thanks for any help.
