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.
