var lighton : boolean

lighton := true
if lighton = true then
   put "The light is on."
else
   put "The light is not on."
end if

lighton := false
if lighton = true then
   put "The light is on."
else
   put "The light is not on."
end if

Also, I recommend adding break to trace your code so you can see what your program is exactly doing in slow motion.

actually it works like

var lighton : boolean := true

if lighton then
   put "The light is on."
else
   put "The light is not on."
end if 


and I think the following works as well

put "is 2 more than 1? : ", 2 > 1

Code:

put "is 2 more than 1? : ", 2 > 1 



how would this work, tony? would you put a variable after this to set it to trur? or would this just put true on the screen? or... I don't know... I cuold just be missing the obvious... but... could you explain?

because 2 > 1 is a boolean statement (it is either true or false right?) it counts a a boolean. So in this case, true would be output onto the screen.

Freakman is right. Any boolean operator (1)



maybe? I don't know. maybe someone could explain this concept's uses, because I really can't see how this would help in most programs.

what use is it to ouput a boolean variable to the screen?
What use is it to output any variable to the screen?

@Hackmaster: can you assign any variable as you did? No, not that way. Instead, you just assign a boolean variable like any other variable.

Alright, thanks... I just can't really see where it would help in a program, outputting true or false for the user to see.

maybe not necessarily for the user to see, but for debugging purposes it is very useful.
