∟"If" Statements

This section describes 4 forms of 'If' statements supported in VBScript. The more complex form is 'If ... ElseIf ... Else ... End If'.

There are 4 forms of "If" statements supported in VBScript:

1. Single-statement "If":

   If condition Then statement

where "condition" is Boolean value, and "statement" specify another statement. The specified statement will be executed, if and only if the specified condition is evaluated to "True".

2. Multi-statement "If":

   If condition Then 
      statement_block (multiple statements)
   End If

The specified multi-statement block will be executed, if and only if the specified condition is evaluated to "True".

3. "If ... Else" Statement:

   If condition Then
      statement_block_a
   Else
      statement_block_b
   End If

Two statement blocks are specified. But only one statement block will be executed based on the value of the specified condition. If the specified condition is "True", the first block will be executed. If the specified condition is "False", the second block will be executed.

4. "If ... ElseIf" Statement:

   If condition_1 Then
      statement_block_1
   ElseIf condition_2 Then 
      statement_block_2
   ...
      ...
   Else
      statement_block_n
   End If
