Getting a command from jass possible?

[darknessfalls]

I have this extremely old map in warcraft 3 that I recently hacked, of course all the triggers are in jass, In this map when selecting a sertan unit and saying a command for example
-admin hero it will spawns a secret hero. Inside this map there is a command and a hero but I have no clue what the words are to spawning it. Is it possible to read Jass and find out what the command actually is?

Hope you understand,

Thanks for the help.
