in reply to (golf)String Concats or: playing with substr()

Sure, as sprintf makes this nice and easy. 
sprintf( "%${length}s", $string );

UpdateYeah, yeah, I meant "s" in the format string instead of "f". Really, I did! (I had to look up what the string code was on sprintf's page!)

    It looks as if this way will take all my strings and turn them into floats if possible. Making them $args{length} long. Which is just weird. I mean, I couldnt get it to work. But then again, you're masem, and I'm one4k4. ;)

    sub format_text {
        my %args = (@_);

sprintf( "%$args{length}f", $args{string} );
}

    I would post results, but the data is sensitive. (SS#'s, names, and such...)

    Hrm, back to said drawing board I go. I was thinking sprintf may help, but wasnt 100% sure. I'm playing around for the rest of the afternoon anyway, so I might as well learn somethin'.

      I suspect that Masem meant to use "%s" rather than "%f": sprintf "%${length}s", $string;

        Or rather:

        sprintf "%${length}.${length}s", $string;

        as it is the number following the dot that gives the maximum field width when using the s. You could also left-justify by throwing a - in after the % if you like.
