Environment

The following system variables ("at variables", or "@-variables") allow you to query (and set) the current OpenInsight environment.

Variable	Description
@ADMIN	The level of the user currently logged on. There are 3 possible values: 0 - User 1 - Administrator 2 - Systems Administrator
@APPID	The fully specified application inheritance chain (@FM-delimited) for the current application. The first name is always the current application, the last name is always SYSPROG, and any other applications inherited are in the middle.
@APPINFO	A field mark delimited array containing information about all applications in the system. In the SYSAPPS file is one row for each defined application. The information for the current application is copied into @APPINFO. The following fields are defined: Field Number - Meaning 1 - Application title 2 - Database ID 3 - Application's inheritance chain (starting from SYSPROG) 4 - Date and time created 5 - Company name 6 - Author 7 - Create permissions (multivalue field) 8 - Abstract 9 - Document references (multivalue field) 10 - Tool types for documents (multivalue field) 11 - Application entry point id 12 - Application entry point class id 13 - Application entry point entity id 14 - Flag for maintaining columns in repository 15 - Logon banner name
@DBID	The name of the current database (same as @APPINFO<2>)
@ENVIRON_SET	Array of environmental settings for the current user.
@FILES.SYSTEM	Field mark delimited array of OpenInsight system files
@FILES_SYSDICT	The file variable for the SYSDICT file
@FILES_SYSENV	The file variable for the SYSENV file
@FILES_SYSOBJ	The file variable for the SYSOBJ file
@FILES_SYSPTRS	The file variable for the SYSPTRS file
@LOWER_CASE	An ordered string containing all lower-case letters. Corresponds to @UPPER_CASE.
@LPTRHIGH	Height of the printer page.
@LPTRWIDE	Width of the printer page.
@MDIACTIVE	The active child from which an event is invoked. An event is invoked from a frame and its active children. The value of @MDIACTIVE is dynamic.
@MDIFRAME	The frame of the window from which an event is called. The value of @MDIFRAME is dynamic.
@PRINTMODE	If this variable is set to false, the BASIC+ Print function will print the ASCII characters zero through 31 using their assigned graphics. If set to true, these characters are not printed, and are treated as control characters.
@STATION	The network station identifier (or null for non-networked versions).
@SYSTEM_TABLES	Contains a field mark delimited list of tables that cannot be detached.
@TABLES	Field mark delimited array of currently attached tables.
@UPPER_CASE	An ordered string containing all upper-case letters. Corresponds to @LOWER_CASE.
@USERNAME	The name under which the current user logged in. If no user name was specific at login, contains the current database identifier.
@VOLUMES	A dynamic array of attached volumes. When assigned from a Basic+ program, a field mark delimited array of filing systems in the format: filing systemlocation is returned. However, if viewed from the debugger System Variables window, @VOLUMES(n) contains the following: Dimension (n)* - Meaning 0 - Dynamic array of attached volumes. Returned when assigning a Basic+ variable to @VOLUMES 1 - Field mark delimited array of volume labels 2 - Field mark delimited array of volume names 3 - Field mark delimited array of multivalued file names 4 - Field mark delimited array of filing systems associated with the volume 5 - Field mark delimited array of handles to the volume map Note: In Basic+ you can assign a variable to one of these dimensioned arrays and return the result. For example, vol_labels = @volumes(1) assigns the array of volume labels to vol_labels.
@WINDOW	The window an event is called from. The value of @WINDOW is dynamic.
