-====== Selective executive_unload ====== 
-Q: //I would like to make a gdx dump of all the sets/​parameters/​scalars of  my model, but I do not want any equations or variables in there at all. ... Currently my gdx dump at the end of the model solve contains the  equations and variables as well.  I really need to get rid of these. Is there a way to do this? //

-I don't know of any way doing this without listing all the (set,​parameter) symbols in an execute_unload statement. If you just do '​execute_unload "​allsymbols.gdx";'​ as your last line, GAMS will export everything (including vars and equs) to the GDX container allsymbols.gdx (similar to the command line parameter '​gdx=...'​). You can empty your variable/​equation symbols, by adding '​option clear=var1, clear=var2, ..., clear=equ1,​clear=equ2,​...;'​ as the last line(s) in your program. Hope this list is smaller and maintainable. You can also write your own GDX utility. There are API files in the 22.7 distribution and example programs, Such a utility could go through an existing GDX container and only copy sets and parameter symbols to the a new GDX  container.
