I'm trying to find a way to list out, or save to an array, the dimensions in a model that reference specific global variables. I am not very experienced with macros and I'm having a tough time figuring out what parts of the API to look into for this functionality. I'm thinking I could potentially accomplish this by checking the other equations and doing string comparisons, but I'm not sure if that will work. Any tips are appreciated, please ask for clarification if I have been unclear. Thanks!
