Subject: undocumented CP/M "feature"

Not only does the "feature" of being able to write files before
opening them exist, but there are actually programs which apparently
use this capability!  We discovered this accidently while building
the MARC CP/M emulator -- a test program failed for no reasonable
reason and it was only after a great deal of searching that the
truth was uncovered.  (Needless to say, we don't support such
a "feature" in the emulator.)

There are programs that are "sloppy" in other ways too, of course.
One very popular CP/M utility has a habit of closing files that
haven't been opened, or closing files more than once.

Jolly good fun.
