SecureCRT支持ActiveX script engines，包括VBScript和JScript (Microsoft’s version of JavaScript)两种脚本。
Note：如果你想使用脚本自动运行方式的话，需要在session option中进行设置。脚本可以用任何文本编辑器来开发。Script头部用来识别脚本语言和SecureCRT脚本接口的版本，脚本头部的每一行必须以#开头，头部包括
$language行和
$interface行。例如，下面是一个简单的脚本。
# $language = "VBScript"
# $interface = "1.0"
Sub Main
' Display SecureCRT's version
MsgBox "SecureCRT version is: " & crt.Version
End Sub 代码通常放在main子过程，引擎在执行main子过程前，将转换并执行全局代码(脚本代码定义在任何子过程之外)，如果你有一些初始化处理的话，可以使用这一特性。
如果想终止main过程，用VBScript的话，可以用Exit Sub语句。如：
Sub Main
condition = DoSomething()
If condition = 0 Then
' Error, bailout
Exit Sub
End If
End Sub SecureCRT有一些内建的对象，可以通过顶级应用对象或子对象调用。这些对象都有一些属性和方法。例如：
Dim dlg
Set dlg = crt.Dialog
dlg.Prompt("Login:")
下面分享给大家一个通过N个跳板机上传文件的FTP脚本：
#$language = "VBScript"
#$interface = "1.0"
Sub main
' turn on synchronous mode so we don't miss any data
crt.Screen.Synchronous = True

' Occasionally, a host needs to be kicked to display a
' login prompt.
