# IfThen

The **IfThen** function checks the expression passed as **AValue**, and returns the value of **ATrue** if the expression is **True**, or returns the value of **AFalse** if the expression is **False**.

* **AValue** is the expression that will be determined to be either **True** or **False**.
* **ATrue** is the string to return if the expression evaluates as **True**.
* **AFalse** is the string to return if the expression evaluates as **False**.

::: info
**AValue** can check anything - but the function is case-sensitive and the match must be exact to return **True**.
:::

**Declaration**: Function IfThen( AValue : Boolean; const ATrue : string; AFalse : string) : string;

A simple example as below.

```pascal
procedure ScriptEvent (var Value : variant);
var
  aStr, aName : string;
  aCount : integer;
begin
  aCount := 1;                              //As a numeric function
  aStr := ifthen(aCount=1,'aCount is 1', 'aCount is not 1');
  LogInfo(aStr);                            //True
  aCount := 57;
  aStr := ifthen(aCount=1,'aCount is 1', 'aCount is not 1');
  LogInfo(aStr);                            //False

  aName := 'Susan';                        //As a string function
  aStr := ifthen(aName='Susan','Susan is in the house!', 'Susan has gotten lost!');
  LogInfo(aStr);                           //True
  aName := 'Fred';
  aStr := ifthen(aName='Susan','Susan is in the house!', 'Susan has gotten lost!');
  LogInfo(aStr);                           //False
  aName := 'SUSAN';
  aStr := ifthen(aName='Susan','Susan is in the house!', 'Susan has gotten lost!');
  LogInfo(aStr);                           //False
  LogInfo('');

 end;
```
