These commands are the core of the scripting system. They allow you structuring your programs, and interacting with the interpreter. Many of them have a special syntax.
Most of these commands have little or no knowledge of the Planets game, for commands to interact with your game, see Global Commands, Ship Commands, Planet Commands, and other sections.
The names of these commands are reserved. You cannot define own subroutines or variables named identical to elementary commands. A line starting with the name of an elementary command is always interpreted as that elementary command, even if there is an Elementary Function of the same name.
