RE: variable vs variant

Hi Ramzi

A Variable is a place to store a piece of information in the computer's memory.

Just as you might store a person's telephone number in your memory, you can store information in a computer's memory. Variables are a way of accessing the computer's memory and setting aside memory space to store the information.

A Variant is essentially a universal data type.

It can contain any kind of information internally, and represent any data type

Regards

Carlos
