Let's not spend time arguing definitions. An integer is a whole number, period. In VFP an integer has a minimum value and a maximum, but that's VFP's own definiotin, or limitation if you want. An integer is by us humans counted in "groups of 10", usually called decimal numbers. A hex value is also a whole number, but counted in "groups og 16", or hexadecimal meaning 16 (hex=6, deci=10). "Group of 10" is not technically the same as "group of 16", but that's really not important. I have a university degree in mathematics, so I know very well what I am talking about. However, it is more than 30 years since I graduated, so I don't remember all the different technincal definitions in detail anymore. But I remember the basic, and an integer value is NOT the same as a hex value. But all programming languages I know, has a transparent two-way conversion, meaning that they can handle both integer values and hex values easily.

NB! I also don't have the ability to explain very well what I mean in english, so please be forgiving.
