system

system is a function built-in to the Hugo engine that calls “low-level system functions.” While it’s certainly possible to just call the system functions by their (built-in) number, including “system.h” will define several constants which act as a key. These functions include:

Value	Constant Name (as defined by “system.h”)	What It Does
11	READ_KEY	Reads keypress (doesn’t pause game)
21	NORMALIZE_RANDOM	Make random numbers predictable (used by HugoFix)
22	INIT_RANDOM	Restore “random” random values(used by HugoFix)
31	PAUSE_SECOND	Pause for one second
32	PAUSE_100TH_SECOND	Pause one hundredth of a second (used by “abuses” like Hugo Tetris)
41	GAME_RESET	Returns true after restore or undo (oddly, it doesn’t work for restarts)
51	SYSTEM_TIME	Stores system time in parse$
61	MINIMAL_INTERFACE	Returns true for minimal ports
