-====== 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 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.
