Complete Function List
For the syntax of each function, refer to the page of the function's type.

Standard functions
break() -- jump out of current loop
continue() -- jump to start of next loop
return() -- exit script
goto(label) -- jump to a label in the script
include(lump) -- read the contents of a lump

print(mess, mess, ...) -- print a message to the console
rnd() -- return a random number from 0 to 255
beep() -- make a beeping sound
clock() -- get the current time (100 clocks = 1 second)
wait(n) -- delay for n clocks
startscript(scriptnum) -- start off a new instance of a script
