in thread Dynamic interpolation in a string with a scalar variable?

OK, I wasn't sure if there was some way to do it that was native to Perl. I will just use a standard function to modify the string. Thanks.

    some way to do it that was native to Perl.

    The "native" way: with a closure:

    my $variable = 3;

my $string = sub { return "Variable: $variable\n"; };
print &$string;

$variable = 4;
print &$string;

    I assume here that by "native" you mean "without using a module". However, be advised that many modules are written using "native" pure perl and that modules are as much a part of the language as the print function.

      Nice, thanks. Yeah, instead of "native," "built-in" would have been more accurate.
