Hi

I would like to make a gdx dump of all the sets/paramters/scalars of

my model, but I do not want any equations or variables in there at

all.

Because our model solves iteratively some the sets/parameters/scalars

get changed as it loops around looking for a solution. I need to

capture the FINAL values after the last solve.

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?

There are hundreds of sets/parameters/scalars so I cannot manually

specify each one for inclusion into the gdx file, and it would become

impossible to maintain and eventually stuff would get left out.

All help appreciated.

Thanks

AndyC

Andy,

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 distribtution 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.
