st: Extracting list of RHS variables after recalling stored estimates?

[Rachel <academicgirl@gmail.com>]

I executed an ML command and stored the results using -estsave-.
Calling -estsave, from()- and -ml display- displays the entire set of
results with the names of the covariates within the table.  However,
I'd like to extract or display the list of covariates (RHS variables)
in each equation in *list* form.  Is this possible?

Thanks,
Rachel
