How to declare variables

Hi, can someone please tell me how to declare the following in vba coding

An integer to use as a counter (e.g. intCounter)
Two integers to use as upper/lower limits for the random number you will generate (e.g. intLower and intUpper)
A Long Integer to hold the cumulative total (e.g. lngCumTotal)
A Long Integer to hold the random number we will generate (e.g. lngRandom)

Thank you
