„ Declaration of table
Format
„ Reference to data within the table
Table name.field name
local “table name” ={field 1, field 2, field 3}
Example 1) Table declaration and initialization
local Product ={ LotNo=123 , Serial No=1001 , name="camera"}
Declares table Product.
LotNo=123
Serial No =1001
name ="camera"
Example 2) Reference to data variables within the table
local a = 0 Declares variable a.
local Product ={ LotNo=123 , Serial No=1001 , name="camera"} Declares table Product.
a = Product.name
Stores the name field of
the table Product in a.

dividing "," (comma).
local “arrayname” ={}
Example
local b ={} Declares array b.
Example
local a={} Declares array a.
a = {3,4,5,6} Assigns the 4 values 3, 4, 5, and 6 to array a.
local b ={16,51,55}
Declares array b and initializes it with the 3
values 16, 51, 55.
local b[3] = 10 Assigns 10 to the third value of array b.
local b[4] = 11
Assigns 11 to the fourth value of array b (adds 1
element).
