How to use the variables

It is not necessary to declare the types of your variables in a George Script.
For instance, you can write the two lines below :


in a script without declaring that the variable MyNumber is numeric or the variable Answer is boolean.

As for commands and instructions, the George language sees no difference between uppercase and lowercase letters. For instance, MyNumber, MYNUMBER, MyNuMbEr are all exactly the same variable.

The George language use a few reserved variables in order to work correctly. You can use them as you wish, but it is not advised to modify them.
That is the case with the two variables Time and Result (encountered in the clock.grg script above) which contains respectively the current time and the results of the last used TVP Animation command.
