Try running the _all_ of the code and looking at the resulting data
*(copy and paste it into the command dialog box and hit return).

You can also read the help page for each and every command by typing
in Stata....

man [command]

I've not got a version of Stata 7 installed that I can check this on,
but on the current install I have (11.0) your first question is
answered in the help page shown when I type...

man clear

Similarly your second question can be answered by typing...

man set

and reading that.  Although in this instance there are lots of
different things that -set- does, and you would have to click through
to the -man obs- page to find the answer.

It sounds as though you would benefit greatly from either the Stata
NetCourse 101 (see ) and/or
one of the many excellent books out there (see / /

"... no scientific worker has a fixed level of significance at which
from year to year, and in all circumstances, he rejects hypotheses; he
rather gives his mind to each particular case in the light of his
evidence and his ideas." - Sir Ronald A. Fisher (1956)
