A method, system, and/or computer program product manages a set of software modules in a software runtime environment, where the set of software modules has one or more dynamic dependencies and one or more static dependencies. Each software module having a static dependency on another software module in a set of software modules is identified. Each subset of the set of software modules that is interdependent with another subset due to static dependencies between subsets is identified. In response to a change in state of a module in an identified subset, the change in state is applied to all modules in the identified subset.

An image display apparatus with a display device for displaying images and a viewing device for viewing an image in the left eye and a different image in the right eye. Two smaller images, a left image and a right image, are created from the same two-dimensional image. The left image includes, as it's left most part, the left most part of the two-dimensional image, the right image includes, as it's right most, the right most part of the image two-dimensional image, and both the left and right images include a common central part of the full image. When the left and right images are displayed such that the left eye sees one image and the right eye sees the other image, the viewer sees the two-dimensional image as a virtual image that can be wider than the viewable width of the display device. The width of the virtual image can be varied to accommodate the viewer.

A system, method and computer program for validating a syntactical statement employing a stored syntax tree which represents all possible syntax options. The tree consists of a network of junction nodes and data nodes between a root node and an end node, whereby all paths through the tree lead to the end node. Firstly, a syntactical statement is passed to the root node, where it is parsed into elementary tokens. Next, a table is created to store the tokens, and entries representing the end node of the syntax. The location of a current node in the syntax tree is also maintained, whereby the current node is initially the root node. Then, the potential nodes that can be selected from the current node and their distances from the current node are returned. The potential nodes are then compared to the stored tokens, and a potential node is selected. Finally, the location of the current node is updated and the process is repeated until the syntactical statement has been validated.

A system and method of recognising command related items in a body of object code, such as command names and/or associated option names involves entering a list of required command names and/or option names in programming language form into a filter table. The object code is then scanned for all bit strings potentially representing command names and identifying such names. For each potential command name, succeeding bits are then examined for bits which represent valid options for each said command name so as to further confirm the identity of commands having valid combinations of command names and/or options. Optionally, the command/option syntax may also be checked. The candiate commands, including options, now identified in programming language form are then compared with the entries in the filter table to determine whether or not they match the required list, which may be further refined by use of logical operators.
