I'm trying to get a script to interpolate variable values in a

It can be done; see the FAQ entry

Gunnar, this works perfectly, and is what I am trying to achieve. Many
thanks, and a brew on me :)

As far as I know, templates require separate files to
work with. To avoid a lot of separate files, I've been using 'here'
documents up until now, all contained in one large script. But I
wondered if I could achieve a similar
effect putting the blocks of text in a __DATA__ block. Now I know it
can be done, so I will be exploring this method.
Not much to explore, really. Did you read the applicable Perl FAQ? Even
if it provides this method, it doesn't exactly recommend it... Besides
full-blown template methods, the FAQ suggests a couple of other methods,
that usually are better, and so is here documents which you say you have
been using.
