The name of the constant.
Data Type: Numeric or String
A constant value, and optionally, the + and - unary operators. Unlike variables, constants must be initialized.
Declares a constant value; i.e., its value can’t be changed throughout the life of the program or routine. One of the ideas of declaring constants is to make code easier to both write and read; it allows you to replace a value with a recognizable word.
The rules for
the same as those of any variable: the name can be up to 255
characters in length and can contain any alphanumeric character
or an underscore, although it must start with an alphabetic
character. As is the case with variable names, these rules can
be overridden by placing brackets around the constant
constantvalue can be a string
or numeric literal. It can be only a single value (a simple
constant); that is, it cannot be an expression that includes a
call to an intrinsic or user-defined function, property, or
method, nor can it contain any arithmetic or string operators or
variables. In addition, a constant can’t be defined in terms of
another constant, as in the statement:
Public Const CDATE = CSTART_DATE ' Invalid
Private Const my_Constant = 3.1417
The recommended coding convention for constants is the same as variables: use camel casing. This places ...
