Re: Could someone explain this variable please

What exactly is this declaring?

somevar:   0..100;

And how and why is it used?

Thanks. 
range used in creating arrays for example.
  instead of having arrays that index at 0
for the first one, you could have an array that
indexes at any starting number you want! this does
not mean that it's actually starting that much higher
in the position of the array how ever.
 1..101 is the same as 0..100 in count.
the difference is, 1 on the first example is
the start of the first item in the array while
0 on the second example is the start of the
first item in the array.
etc//
  its also used in sets, range comparing! for
example
 if SomeVariale in [10..40] then ...
 which means if the Variable value falls in that
range then its true..
et.c..
