Hello

   eval EXPR
   eval BLOCK
      In the first form, the return value of EXPR is
      parsed and executed as if it were a little Perl
      program.

So, to return "foo has value $foo" after interpolation, you can do:

my $foo = 7;
my $str =  eval '"foo has $foo"';
print $str;

Notice the additional double quotes inside the single quotes. This makes eval evals

"foo has $foo"

and returns the resulting string. If you don't include the additional quotes, eval evals

foo has $foo

which is not what you want.

Hope this helps,,,

Aziz,,,
