You may then enter the values all at once or one at a time. To enter values all at once, separate them by
commas. (If your string literal includes leading blanks, colons, or commas, you must enclose the string in
quotes.)
To input a string with no ? displayed, use LINEINPUT.
100 LINEINPUT A$
POS(x)

Built-in Roku Object and Miscellaneous Functions
Roku BrightScript has integrated support for Roku Objects. These objects are how the Roku system exposes
blocks of functionality to the scripting language. For example, there are objects for receiving events (aka
messages), accessing consoles (such as the serial port), playing back video, playing audio, etc. See the
separate Roku Object specification for the details.
The following built-in functions are for manipulating Roku Objects and Miscellaneous functions.
WAIT
LISTDIR
CREATEOBJECT
GETINTERFACE
OBJFUN
TYPE
SLEEP
wait (timeout, object)
This function waits on objects that are “waitable” (those that have a MessagePort interface). It returns the
message object. If timeout is zero, “wait” will wait for ever. Otherwise, Wait will return after timeout
milliseconds if no messages are received. In this case, Wait returns a type “
rotINT32 ”.
Example:
p = CreateObject("roMessagePort")
sw = CreateObject("roGpioControlPort")
sw.SetPort(p)
msg=wait(0, p)
print type(msg) ‘ should be roGpioButton
print msg.GetInt() ‘ button number
