### Parameters

* **Condition** *\<unquoted string> -* This parameter indicates a condition or conditions that is evaluated.

### Usage

Consider the following variables and respecting values:

| **Variable** | **Value**    |
| ------------ | ------------ |
| VAR(0)       | 1            |
| VAR(1)       | 2            |
| VAR(2)       | 10           |
| VAR(3)       | <p>0<br></p> |
| VAR(4)       | ""           |

#### **Example 1**

```
If(VAR(0)=1 AND VAR(2)=2)
Set Value(VAR(0),Numeric, 4)
Else
Set Value(VAR(0),Numeric, 40)
End If
```

*Result:*

| **Variable** | Value |
| ------------ | ----- |
| VAR(0)       | 40    |
| VAR(1)       | 2     |
| VAR(2)       | 10    |

#### **Example 2**

```
If(VAR(0) <> 1)
Set Value(VAR(0),Numeric, 4)
Else If(VAR(1) > 1 AND VAR(2) < 50)
Set Value(VAR(0),Numeric, 40)
End If	
```

*Result:*

| **Variable** | Value |
| ------------ | ----- |
| VAR(0)       | 40    |
| VAR(1)       | 2     |
| VAR(2)       | 10    |

#### **Example 3**

```
If(VAR(3)= VAR(4))
```

*Comparison made is **0** = **""** and the result **is ""***\
\
**Return**: True

#### **Example 4**

```
If(VAR(4)= VAR(3))
```

*Comparison made is **""** = **0** and the result is **"0"***\
\
**Return:** False

Each *If* action must have a corresponding *End if* action.

When the operands are of different types (numeric, string), the second operand is converted to the type of the first (See **Example 3** and **Example 4**).
