====== Conditions ======

Here is one and only conditional statement:

<code>
If <expression 1> Then
  ...
ElseIf <expression 2> Then
  ...
Else
  ...
EndIf
</code>

In conditions, you can use any valid [[expressions|expression]], the result of which is equal to “true” or “false”. For true, a string equal to "1" is taken, for a false - "0" or an empty string.

Unlike expressions in command parameters, an expression in conditions is written without quotes with % sign in front of them:

<code>
If %AUTORUN_TCARCH% = 32 Then
  ...
EndIf

If FileExist("%COMMANDER_PATH%\NoClose.exe") Then
  ...
EndIf
</code>

**Legacy command use**

In Autorun before version 2.0.10, only certain special functions could be used in conditions, while the condition was limited to one function. In later versions, this option is left for compatibility.

<code>
If [Not] Function1 <parameters> Then
  ...
ElseIf [Not] Function2 <parameters> Then
  ...
Else
  ...
EndIf
</code>

It's allowed to use both expressions and function in one condition (but in different branches).
