* add binary (computational-x with x=1,2,3,5) variables. Only comp-3 is
currently implemented. Some redesign/implementing of the move and accept
functions is needed. Decimal point is still hardwired in those routines.
* implement inspect and string verbs.
* change CHANGES to ChangeLog, in the format of gnu standards, so we can
benefit from some automation in SourceForge releases. For the same reason,
create a NOTES file.
* Include the sources of db-1.85 in our distribution to become easier the life 
for users of RedHat, Caldera, and others Linux distributions. To avoid clashes
with previous libdb installed, we could rename our own library (?).
* Make an ESQL SECTION to make happy all SQL implementors.
* Re-implement all "move" function, as well as the "display" to use (n)curses,
terminfo and other system-independent terminal functions.
* implement  sort...using...giving
* introduce "alternate key" in file ops
