SYS Object

Biz / Browser builds a SYS object under the Root object at startup. It is generated before the application’s CRS is loaded, so it can always be referenced in “//.SYS”.

The SYS object is read-only. You cannot change the value, delete it with the Delete method, or add a subordinate object with the Append method.

The properties of the SYS object are described below.

Name	Type	Description
OS	String	A string that identifies the client OS Functions have been expanded since to support 64bit OS
OS_VERSION	Number	Client OS version number
CLIENT	String	Client browser name
CLIENT_VERSION	Number	Client browser version number
PROXY	String	Proxy server host name
PROXY_PORT	Number	Proxy server connection port number
SERVER	String	Server host name
SERVER_PORT	Number	Server connection port number
USERNAME	String	(Always blank. It is left for compatibility with the past. The Windows login user name can be obtained with the Runtime.GetUserName method.)
APPROOT	String	(Remained for compatibility with the past)
HOSTNAME	String	Client computer name
MODELNAME	String	Manufacturer name, model name, etc. (manufacturer setting value) Supported by and later version, and
PLATFORM	String	Platform type Supported by and later version, and
DEVICEID	String	Device unique ID In the Mobile version, the value is not guaranteed for Windows CE 5.0 or earlier models ( excluding Windows Mobile ). A valid value is set only if the WindowsAPI KernelIoControl IOCTL_HAL_GET_UUID option is supported. In the Android version, you can get the serial number set on the device. Supported by and later version, and
LANGUAGEID	Number	You can get the language ID ( locale ID / LCID) of the running OS . Using this value makes it possible to determine the operating language in the CRS and branch the process. Added since

Usage Example

var message = strf("OSは %1 です", //.SYS.OS);
var title = strf("%1 Ver.%2", //.SYS.CLIENT, //.SYS.CLIENT_VERSION);
MessageBox(message, title);

The SYS object is no longer deleted when the DeleteChild method is executed on the Root object from Ver.5.0.0, Mobile Ver.4.5.0.

APPROOT Property

The APPROOT property is left for compatibility with past Biz / Browser . Avoid using this property as much as possible.

Get and set the position to be treated as “/” in the resource on the server. The value of this property can be changed exceptionally.

For example, if “/ APP1” is set and Get (“Proc1”) with a relative path, the request will be sent at the URL http: // server-name / APP1 / Proc1. Also, if you use Get (“/ Proc1”) with an absolute path, the request will be sent at the URL of http: // server-name / Proc1.

Starting with version 3.0, the APPROOT property must be downloaded by the same protocol, server, and port as the primary session (protocol, server, port when logged in) and the APPROOT property is specified. Use to determine the URL. Other than that, the URL is determined based on the specifications of the Get method.

Note that the URL in the CAR file is also affected by the APPROOT property, so setting the APPROOT property will almost always prevent the CAR file from loading as intended. Therefore, APPROOT cannot be specified and CAR files cannot be used at the same time.
