The issues here were discussed in my posting last Friday,
and in some previous postings.
There are several ways to handle this problem
and the one I have chosen is driven partly by
my own convenience -- but not only.
1. -regplot7- is indeed now available from -ssc inst regplot-
for those still using Stata 7. It is just the old -regplot-
renamed. This is flagged in the package write-up. Your fellows
may use that. You may use that for speed. This is dead code
so far as I am concerned, although any who find it useful
2. Rewriting these programs is more than just changing the
graphics calls, in exactly the same way that the new graphics
is not a one-to-one translation of the old. Many small and
large details are changed. Indeed "update" is here
understatement in some cases. The syntax and functionality
also differ in various ways. In the case of -regplot-, the
previous version carried a -separate()- option; in the latest,
for various reasons, this is dropped. Such differences need
not rule out, absolutely, the code for two versions co-existing
within the same .ado file, and that's often a very good idea
indeed. Nor does it rule out the help for two versions
co-existing within the same .hlp file. However, I judge that the
latter could be very confusing, and that alone determines
the matter so far as I am concerned.
