Yes. That was the issue. Thank you kindly. An encryption program, naturally, must expect to read in files of whatever type.

What I'm hoping to do is recreate in Perl an encryption program which I had written long decades past and subsequently lost. The original was among many which I had authored in JForth on an Amiga 2000. Those I had preserved for ten years or more on a CDROM but now cannot find that disk anywhere.

I have all but entirely forgotten Forth, and my Perl has also grown rusty. Being now retired, I have elected to refresh myself in both as hobby projects. Again, I thank you for your indulgence.
