OrdersBar.cfg file question

[lexloma]

Here's a snippet of code from OrdersBar.cfg:

Button10Type=Checkbox
Button10CommandWhenClicked=Toggle_silent_running
Button10CommandToCheckIfIsChecked=Is_Silent_mode_A ctive
Button10CommandToCheckIfIsEnabled=Is_Underwater


I searched and found that the commands used in OrdersBar.cfg are defined in SH4\Data\Cfg\commands.cfg file (for instance, "Toggle_silent_running", above).

My question is: where are the commands such as "Is_Silent_mode_Active" and "Is_Underwater" stored? These are the commands that let you test whether a given command is checked, enabled, etc., but for the life of me I cannot find where they are stored/defined.

Anyone know?
