Thomas:

A constant is just like a variable, in that it can be assigned a value by
the programmer,
but once assigned, it can't be changed like other variables can:

constant pi = 3.141529
----------------------------------

A procedure is a named routine which accomplishes some task; whenever you
call it by putting its name in your main line of code, it activates the
routine:

procedure Add(integer a, integer b)
  print(1, a + b)
end procedure

-- to use it:
Add(1,1)-- screen shows "2"
-------------------------------------

A function is a named routine which returns a value when called:

function Added(integer a, integer b)
   return a + b
end function

-- now use it:
x = Added(3,4)-- x would be 7
----------------------------------------------------

As for your last question,
"Also, I'd like to know what the difference between " and ' is.",
you'll have to finish it first!  :)


HTH,
Dan

Can someone tell me and give me an example of; a constant, a procedure and a
function. Also, I'd like to know what the difference between " and ' is.
