set up an ASP program

An ASP program is a text file with an. asp extension, including text, HTML statements, ASP commands, and other scripting languages.
ASP commands must be placed between "<%" and "%>"

Program Annotation

In order to develop a good programming style, a modest annotation is necessary, the ASP provides two ways to annotate

1, but the quotation mark (), after the single quotation mark this line of text is considered as a comment
2, REM keywords, in rem after the text, as a comment

Assignment statement

The assignment statement of general variables in ASP is "="
And the object is assigned with the SET statement.

=	Equals
<>	Not equal to
The	Less than
>	Greater than

logical Operators

The logical operators for ASP are:

1, not to reverse the logical value
2, and "and" or "and" operations.
3, or "or" operation
4, XOR "exclusive or" operation
5, EPV judge two expression logic equal, the same result is true, otherwise false
6. IMP determines whether two expressions are logically related

string Operators

The ASP has only one string operator, which can force two of expressions to do string concatenation

Variable Declaration

Variable declaration must be noted

1. A valid variable name cannot be greater than 255 characters
2. The variable name must begin with a letter
3. The variable name must be unique within the same valid range

Variable declaration DIM variable name
Constant declaration CONST Constant name = constant value

Data Type

For the ASP, it has only one variant (universal variable) data type, which is a very special type of data, and you can assign any data type to such variables as Boolean, Byte, Integer, Long Integer, single-precision floating-point number, double-precision floating-point number, currency, date, and so on.
