Hi,
Is there a way to change the label of a set in a gdx file?
I want to do something similar to the example in https://www.gams.com/latest/docs/T_GDXRENAME.html but instead of changing the names of the values of the set, I want to change the label.
I have tried something like:
Set c / r, g, b, y /;
Parameter A(c);
A(c) = ord(c);
execute_unload 'data.gdx', A;
execute 'gdxdump data.gdx';
Set map(*,*) / c.colour /;
execute_unload 'map.gdx' map;
execute 'gdxrename data map';
execute 'gdxdump data.gdx';
I want this to give A(colour) as the label in the gdx file. But it is still A(c).
