system.h

This header file defines some constants that are used with the system() routine. It offers low-level access to the Hugo system.

Syntax for using the system routine is system(<function>)

Function	Description
READ_KEY	Reads a single keypress (useful if you want to create a “press any key to continue” prompt)
NORMALIZE_RANDOM	Make random values predictable. Use this if you are testing your game.
INIT_RANDOM	Restore the randomness of the random number generator.
PAUSE_SECOND	Pause for one second
PAUSE_100TH_SECOND	Pauses for 1/100th of a second.
GAME_RESET	Returns true if the game after a RESTORE or UNDO command.
SYSTEM_TIME	Returns the current time on the system the game is being played on.
MINIMAL_INTERFACE	Returns true for minimal ports of the game engine.

Time-keeping

system.h also has some extra time-related stuff, including:

• a string array called “_time_string” that can be used to store time-related strings (up to 19 characters).
• some enumerated constants and a routine called GetSystemTimeValue, which writes only the specific time metric (the second, minute, hour, day, month, year) to _time_string.
