* Say exactly what you typed and exactly what Stata typed (or did)
in response. N.B. exactly! If you can, reproduce the error with one of
Stata's provided datasets or a simple concocted dataset that you
include in your posting.
Don't send examples like this, which gives no information:
o The command -fiddle- worked yesterday, but it is not working today.
or like this, which gives very little information:
* I am using -frog-, but I just get the message "invalid syntax".
This example shows better style, setting aside the fact that its
answer can be found in the online help:
* I am using Stata 9 to try to draw a plot using -scatter-.
Here is an example showing my problem with the auto data:
. scatter mpg weight, s(p)
I get lots of very small points. Why doesn't Stata use plus symbols?
