I'd like to be able to find the name of a macro that contains a given
string.  After -anova-, there is a list of ereturn macros that contain the
name of the term in the model and the number assigned to the term
by -anova-.  I want to be able to do arithmetic on the scalars (sum squares
and degrees of freedom) associated with that term's number by referencing
the model's term.
Example:  Let's say -ereturn list- after -anova- shows
. . .
e(term_1) : "clinic"
e(term_2) : "physician|clinic"
. . .
I would like to write a program with a syntax of, say,
-satterthwaite clinic physician|clinic . . .-
and have the program query -anova-'s ereturn macros in order to get the
names of the macros corresponding to these terms.  I can then parse the
numerals from the macro names in order to look up the corresponding ereturn
scalars, e(ss_1), e(df_1), e(ss_2), e(df_2), . . ., and do arithmetic on
them.
I've scanned through the ado-file for -test- (perhaps it's in -_test-), and
looked at -help macros-, and its linked help files, but nothing jumped out
at me.  I can always use brute force to go through the list of ereturn
macros in a loop, or concatenate their contents in-sequence (again, a loop) 
and use -posof-.  But is there anything more direct?
