That's good to know. Admittedly a corner case, but: suppose I did
something silly like
<script>
nulldata 48
setobs 12 1990:1
x = normal()
sdx12 = sdiff(x)
setobs 4 1980:1
sdx4 = sdiff(x)
<script>
would everything be ok?
I'm reminded of that nice quotation from Babbage:
"On two occasions I have been asked [by members of Parliament],
'Pray, Mr. Babbage, if you put into the machine wrong figures,
will the right answers come out?' I am not able rightly to
apprehend the kind of confusion of ideas that could provoke such a
question."
;-) Will try to respond to the substantive points soon.
