    Sorry, but where exactly did you say that?

    Hi all

    I am trying to concatenate a string and a value of a variable to construct the name of a known variable.

    For example: 

    $foo="foo";
$bar="f";
print ${$bar.'oo'}

    [download]

    should give out: "foo" but it doesn't.

    Now, before you say anything, yes, I know, I should use a hash instead, but humor me, would you ?

    Thanks

      In the OP's defense, it was in response to me after you replied to their original posting. Just a race condition and small bout of carelessness on the OP's part.
