1. Modifying variables
An atom is anything an integer is and more.
A sequence contains atoms. A sequence can contain
other sequences but at some point must be either empty
or contain atoms.
An object is either an atom or a sequence. It is
free to be either.
Sequences can not be atoms and atoms can not be
sequences.
Integer are only whole numbers.
Example integers: 1, 2, 3, 4, 5, -15, 145, 90734.
Integers are limited to 31-bits.
atom a
integer i
sequence s
object x
a = 0.333333333333
a = 3216542154
a = #FFFF
a = 32452340987.234545
a = -345345.3423
i = 5+6
i = 'A'
i = '$'
i = '1' + '2'
i = 134345
i = -134134
s = {1, 2, 3, 4}
s = s + 1-- same as
s = {1, 2, 3, 4} + 1 --also same as
s = {2, 3, 4, 5}
s = -s -- same as: s = {-2, -3, -4, -5}
s = "ABCD" -- same as: s = {'A', 'B', 'C', 'D'}
s = "ABCD" -- same as: s = {65, 66, 67, 68}
s = {"AB", "CD", ""} --same as: s = {{65,66}, {67,68}, {}}
s = {1, 2, 3, 4}
s[1] = 5-- now s = {5, 2, 3, 4}
s[1..3] = 7 -- now s = {7, 7, 7, 4}
s = {"This", "and", "That"}
s[1][1..3] = "Kis" -- s[1] = "Kiss"
x = s
x = a
x = i
I hope this abundance of examples helps clear things up.
IF not. Please post a little more specific question.

You surprise me; I never thought of this kind of arithmetic. But for a
newbie this must be a bit confusing. The result i is the number 99, and how
is that done?
Well, in Basic you could write this as ASCII('1') + ASCII('2'), or something
like that!
Now do you understand that the result is 99?
