Defined in macros/scripts/events.asm and engine/overworld/scripting.asm:ScriptCommandTable.
Until this document is filled out, the G/S Scripting Compendium has descriptions for most of these commands. It was written for G/S binary hacking and not Crystal assembly hacking, so it's not 100% accurate for pokecrystal.
