~~Title: OnScriptCommand ~~
<pageheader/>

The **OnScriptCommand** event is the entry point for an [[:scripting:example_scripts:adding_a_new_internal_command|internal command]] added by a [[:scripting:script_add-ins|script add-in]]. The actual name of the event is defined by the script itself, when the command is added via the **[[..:scripting_objects:scriptinitdata|ScriptInitData]].AddCommand** method - **OnScriptCommand** is merely a placeholder name.

$$ (#)**Method Name:**
$$ OnScriptCommand
$$ (#)**Argument Type:**
$$ **[[..:scripting_objects:scriptcommanddata|ScriptCommandData]]**

$$ //bool//
$$ (#)**Description:**
$$ When a script add-in adds a new internal command using **ScriptInitData.AddCommand**, it specifies the name of its entry point with the **ScriptCommand.method** property. When the internal command is run, Opus will call that method within your script.\\
The **ScriptCommandData.func** property provides information about the command environment (including any parsed arguments), and the **cmdline** property provides the raw command line that invoked your command.\\
If this event returns **True** the function will be aborted - you might do this if an error occurs and the user chooses to abort the operation.
