Asp Syntax in ASP
Sure! Here’s a quick overview of the syntax basics in Classic ASP (VBScript) to get you started:
ASP Syntax Basics
Classic ASP primarily uses VBScript as its scripting language, embedded inside <% ... %> blocks.
1. Script Block
<% ' Your VBScript code here%>2. Output to Browser
<% Response.Write "Hello, World!"%>or shorthand:
<%= "Hello, World!" %>3. Comments
' This is a single-line commentNo multi-line comments in VBScript.
4. Variables
Dim namename = "Alice"No explicit type declaration — variables are variants.
Use
Dimto declare variables.
5. Data Types
String:
"text"Integer/Double:
123,3.14Boolean:
True/FalseDate:
#2025-05-30#Variant (default type)
6. Operators
| Operator | Description |
|---|---|
= | Assignment |
+ | Addition or concat* |
& | String concatenation |
-, *, / | Arithmetic |
And, Or | Logical operators |
= (in condition) | Equality test |
*Use & preferably for string concatenation.
7. If...Then...Else
If x > 10 Then Response.Write "Greater than 10"ElseIf x = 10 Then Response.Write "Equals 10"Else Response.Write "Less than 10"End If8. Loops
For loop
For i = 1 To 5 Response.Write i & "<br>"NextWhile loop
While x < 10 Response.Write x x = x + 1WendDo While loop
Do While x < 10 Response.Write x x = x + 1Loop9. Functions and Subroutines
Sub SayHello(name) Response.Write "Hello, " & nameEnd SubFunction Add(a, b) Add = a + bEnd FunctionSayHello("Bob")Response.Write Add(5, 3)10. Including Files
