Why not use

  load (sprintf ("%s%.6f.dat DE", savename, s));

instead?  Then, it seems to me that you could use

  feval ("load", sprintf ("%s%.6f.dat DE", savename, s));

as an equivalent way to do the same thing (still in the scripting
language).

You should be able to do the same in a .oct file using the C++
interface for eval, but it might not do what you expect, since
load attempts to insert variables in the current symbol table.  If
your .m file defines a function, the varibles would be loaded in the
local symbol table of the function, but when you translate it to a
.oct file, that function doesn't have its own symbol table.  So where
do you want the new variables to appear?
