ASP Simple Declaration variables

1. Declaration of simple variables
2. Declaration of an array variable
3. Assignment of variables
4. Scope and lifetime of variables
Instance:
Example8.asp
<%
X=1
Call setprocedurevariable ' calls the setprocedurevariable process
Response.Write X ' Displays the value of X on the page
Sub Setprocedurevariable () ' Define procedure
x=2
End Sub
%>

Example9.asp
<%
Dim x ' defines script-level variables
X=1 ' initialization variable
Call setprocedurevariable ' calls the serprocedurevariable process
Response.Write X ' Displays the value of X on the page
Sub Setprocedurevariable () ' Define procedure
Dim x ' defines process-level variables
x=2
End Sub
%>
Example Three

<%

Dim name

Name= "Donald Duck"

Response.Write ("Www.111cn.net My name is:" & name)

%>
One is an explicit declaration, which means declaring a variable using Dim public Private

Dim A, CC, FF
A = 1
c = 3
Public B, E
b = A
Private C, D
c = b

Wait

The other is implicitly declaring in a program, for example, that a variable is used directly without declaring

tt = 2

<%
Dim num ' Declare variable
num=10 ' initialization variable
Response.Write ("<center><font size=10>") ' Set alignment and font size
Response.Write ("num=" &num) ' displays the value of num on the Web page
Response.Write ("</font>")
%>
