Declaring Variables

[kelly mort]

Hello Geniuses,
I need clarification to which variable types to use: Integer vs Long. When do I use long? I am confused. I am thinking maybe where I have used long, I may be using Integer instead.
Thanks in advance.
Kelly.

PS.
Also when I declare almost all my variables at the top of my module, I understand these variables are held in memory as long as the module is active. Does this practice have any downside on memory?
Thanks again

On modern computers Integers are stored as Long Integers and so there is no advantage of using Integers unless you specifically want to restrict the range (there is even some evidence that even when it is in the range of an Integer it is more efficient to use Long now).

I only ever use Long these days.

Also when I declare almost all my variables at the top of my module, I understand these variables are held in memory as long as the module is active. Does this practice have any downside on memory?

If it does it would be miniscule but someone else might have some more enlightenment on this subject.

Oh okay this is very cool info . Just like mark said. That means using Integer will be rather slower . Due to system converting it to Long. Thank you
