This is a table of global variables in SimCity 2000 that have been at least partially reverse engineered and given names. It is probably going to be unpleasant to update, but at least it looks nice and you can sort it.
Data about where in the MISC chunk certain variables are located is from dfloer's sc2k-docs repository on GitHub (CC BY-SA 4.0).
