How can I use a variable as a variable name in Perl?

Question

I need to achieve the following in perl

printmsg(@val1, $msg1) if @val1;
printmsg(@val2, $msg2) if @val2;
printmsg(@val3, $msg3) if @val3;
printmsg(@val4, $m

You can't just string variables together like that and get a resulting variable. You COULD evaluate the expression of $msg + i, but it's probably better if you make msg an array and just index: $msg[$i].
