auto scope question?

[WhatMeWorry via Digitalmars-d-learn]

I'm naturally getting a undefined identifier `s` error in the 
return.  Is there some way to refactor my code?  I tried to 
declare s outside of the else brackets like:

auto screen = executeShell(cmdLine);
auto s;
...
{
    s = screen.output.findSplit("REG_SZ");
}
but that doesn't compile either.



string[] getPath(string cmdLine)
{
    auto screen = executeShell(cmdLine);
        
    if (screen.status != 0)
    {
        writeln(cmdLine, " failed");
    }
    else
    {
        writeln("screen.output = ", screen.output);   
        auto s = screen.output.findSplit("REG_SZ");
        writeln("s[0] = ", s[0]);
        writeln("s[1] = ", s[1]);
        writeln("s[2] = ", s[2]);             
    }
    return (s.split(';'));  // Error: undefined identifier `s`
}
