No, no, that's cheating.

You cannot predeclare my ($A,$B) as you are not supposed to know what's in the data-file. It could be any variable name and any value.

However, the eval suggestion is a good one. How about:

$name ='A';
$value =10;
$string = 'my $' . $name . '=' . $value . '; print "result inside eval
+: $A\n";';
eval ($string) or die "ERROR: $@";
print "result outside eval: $A\n";

As can be expected the lexical declaration does not survive outside of the eval though :-(
