You are correct:) Thanks for your kind words. JB Doriano Blengino wrote: jbskaggs ha scritto: Thank you, I shall search more.

Re: [Gambas-user] In Plain English- A definition of the Datatypes please?
Hi! For me, because of my experience, documentation of datatypes is self evident. I think you should be more precise with your question. What you don't understand? Short, integer and long are pretty much all same thing, but they can hold different maximum (and minimum [negative]) values. Short, integer and long can contain only whole number, so example 3.1415 cannot be stored to integer type variable. Byte is like above, but it can't contain negative values. Byte is also used as size unit, because it always means 8 bit (bit means one state, which can be 1 or 0 [ see: http://en.wikipedia.org/wiki/Binary_numeral_system ]). So, if you need to store value of Pi, you need float type of variable. These are single and float. They are different not only for maximum values, but with accuracy to describe given value. See http://en.wikipedia.org/wiki/Floating_point . Rest are basically just different amount of bits too... but you need more deep understanding of computers. For this moment I can't figure how to explain concepts like pointers with simple terms. You must study. Wikipedia and google is your friend. Hope that helps!

NULL 4 bytes Pointer A memory address. 0 4 bytes on 32 bits systems, 8 bytes on 64 bits systems. For a novice like me I have made assumptions for the past year that turned out to be wrong and I would like to make sure I grasp what this is saying and not assume I do.
