interpolation

[The Ghost]

I want to pull some text from a database:

RxNumber in (select RxNumber FROM restoreReports WHERE Status in  
$Status)

then I want perl to use this string and interpolate the variables  
($Status).

so:

my $Status= "('New','Old')";
my $sql=get_SQL_String(); #will get 'RxNumber in (select RxNumber  
FROM restoreReports WHERE Status in $Status)'
....
....
something.....
print $sql;

# should print:

RxNumber in (select RxNumber FROM restoreReports WHERE Status in  
('New','Old'))


What can I do?
