Variable Definition Syntax

C# variable definition =
    [auto | extern | static] [const | volatile]
    C numeric variable | C character variable
  | C derived variable;

C# numeric variable =
    {long | short | int | decimal | double}
    {variable name [initial value] }.,..

C# character variable =
    char [CHARACTER SET [IS] character set name]
    {variable name {length} [initial value] }.,..

C# derived variable =
    { VARCHAR [CHARACTER SET [IS] character set name]
    {variable name {length} [= character representation... ] }.,..} |
    { BIT{variable name {length} [= character representation... ] }.,..}

The length is the fixed length or the maximum varying
length of the string, and the character representation
sequence is an optional initial value.
