Martin - Yes, it was gross ignorance. That program was written in 1996,
when I didn't know much about programming with a -clear- option. Back
then, I didn't know the difference betwewen a ".do" and an ".ado" file,
so I made everything an "ado" file, which then put it into my ado path
without my realizing it.  I shudder to think how many others like this
are lurking in those old files!

No intrusion into Alan`s work practices intended, but I have a hard time
imagining that you would have a -prog- on your ado-path that -drops
_all- without at least the -, clear- option being present...
