I get an error when running code snippet A, but if I change it to B, there's
no error. I'm not familiar enough with Ruby to know why this is. Could
someone explain this?

----- A -----
def ReturnString ( )
    return "abc"
end

File.open ( "junk.txt" , "w" ) do | f |
    f.write ( ReturnString ( ) + "\n" )
end

----- B -----
def ReturnString ( )
    return "abc"
end

File.open ( "junk.txt" , "w" ) do | f |
    s = ReturnString ( )
    f.write ( s + "\n" )
end

If it makes any difference, I'm running Ruby under Windows.
