The problem shows up on DRACO-2.ARC and DRACO-3.ARC.  Both ARCs
extract perfectly with the MSDOS ARC512.EXE or PKXARC.COM programs.

I have notified the author of the CP/M UNARC program, Bob Freed.  He's
going to look into a fix.  It's somewhere in the UNcrunch routine.
I'll keep you posted on his progress.

Hang on to your DRACO ARCs.  They ARE good.
