in reply to eval & variable names?

When $v contains "a", you want to execute 
$a = $a * 2

Which you means you have to build that string and pass it to the parser (eval EXPR). That can be done using the string literal 

"\$$v = \$$v * 2"

So you want 

eval "\$$v = \$$v * 2; 1" or die $@;

    Thanks!

    I see that I need to look at the string being passed to eval().

    Thanks, again for slapping me back to reality. I guess it's getting late...
