Debugging tools for Windows, scripting with JavaScript: object model

host

The host object can be examined with the dx command after loading a script, using the @$scriptContents variable:
0:007> dx -v @$scriptContents.host
@$scriptContents.host : [object Object]
    currentApiVersionSupported : [object Object]
    currentApiVersionInitialized : [object Object]
    diagnostics      : [object Object]
    metadata         : [object Object]
    typeSignatureRegistration
    typeSignatureExtension

    namedModelParent
    functionAlias
    namespacePropertyParent

    parseInt64
    namespace
    evaluateExpression

    getModuleSymbol

    memory           : [object Object]
    typeSystem       : [object Object]
    ToDisplayString  [ToDisplayString([FormatSpecifier]) - Method which converts the object to its display string representation according to an optional format specifier]

host.namespace.Debugger

host.namespace.Debugger can directly be accessed with dx Debugger:
0:007> dx -v @$scriptContents.host.namespace.Debugger
@$scriptContents.host.namespace.Debugger
    Sessions
    Settings
    State
    Utility

0:007> dx Debugger
Debugger
    Sessions
    Settings
    State
    Utility

host.namespace.Debugger.Utility.Control.ExecuteCommand

Another interesting Object/method is host.namespace.Debugger.Utility.Control.ExecuteCommand which allows to execute commands such as g (go):
if (…) {
   host.namespace.Debugger.Utility.Control.ExecuteCommand("g");
}
