Conventions In Corona

Names or Identifiers in Lua can be any string of letters, digits, and underscores, not beginning with a digit. The following keywords are reserved and cannot be used as names:

          and     break        do        else     elseif      end        false
          for    function    if           in         local       nil          not
          or       repeat      return     then     true        until        while

The following strings denote other tokens:

            +        -         *        /     %       ^        #
           ==      ~=       <=      >=       <        >       =
           (     )        {     }     [     ]
            ;     :        ,     .     ..    ...

Lua is a case-sensitive language.
Global variables:
Identifiers starting with an underscore followed by uppercase letters (such as _Global) are reserved for internal global variables used by Lua.
Comments:
A comment starts with a double hyphen (--) anywhere outside a string.
You can comment out a full block of code by surrounding it with --[[..........]].
To uncomment the same block, simply add another hyphen to the first enclosure, as in
---[[.

      
    --single line commented out
    --[[ entire block commented out
         print( 10 )
         print( 15 )
      ]]

A numerical constant can be written with an optional decimal part and an optional decimal exponent. Lua also accepts integer hexadecimal constants, by prefixing them with 0x. Examples of valid numerical constants are:
3 3.0 3.1416 314.16e-2 0.31416E1 0xff 0x56 5 3.0 5.14 2314.16e-2 0.3456E1 0xff 0x56
