Well, Bob isn't around much anymore, and Alan insisted on advising people
to write it in C#, so ... :-)

Yes. And no.
Yes, you can use the FILENAME PIPE engine to feed the STDOUT of the
Perl process directly into a data step.
But no, if you are on a Windows machine, the pipe writes to a temporary
file, so you can't completely avoid that 'duplicate file on the hard drive'
issue.
If you're on a unix box, the pipe works just the way you want.
HTH,
