SharedARK currently provides extensibility through textual programming. Objects or buttons can be created or modified by writing appropriate Smalltalk code. More in keeping with the metaphor would be to abandon text completely, and do extensions by directly manipulating the SharedARK objects. This also has been tried. Problems with these approaches will be discussed in section 4. 

To obtain the required product yield, the reaction substructure search is combined with a textual search using the queiy builder" of the MDL" ISIS program. 

In short, a package can contain any formal or informal description, program code or model, and textual or pictorial statements (see Figure 7.2). 

Design and implement a program for manipulating shapes. Different shapes are displayed differently. When a shape is displayed, it shows a rendering of its outline and a textual printout of its current location in the largest font that will fit within the shape. 

Validation-Argument Question 3 How can placement program training recognize and distinguish between textual and contextual evaluative criteria ... 

Placement program training should more explicitly focus on the distinction between textual and contextual criteria and how both are related to the curriculum. Broad s (1997, 2000, 2003) studies and other prominent studies in exit assessment (see Haswell 1998, 2001 Huot 1993) have established that contextual factors, factors outside of the actual text, influence assessment decisions. Even in this study, a study that focused exclusively on placement assessment, evaluators read essays cold-without any prior knowledge of the writers-yet they still used a variety of contextual criteria that invoked images of the writers. 

Obtaining a comparison is only half the battle, however. The programs previously discussed produce textual outputs, in various formats. Direct interpretation of these is time-consuming, and can be complicated. Displaying these results in a graphical form provides a far more readily interpreted set of results. 

A message box is primarily used to provide textual and/or numerical information to the user it can also carry logical information back to the program that issued it. Message boxes figured prominently in sections 10.1 and 10.2. In their most basic form they have the syntax... 

Input boxes are meant to provide textual and/or numerical information to the program. Apart from a prompt, as in the Message Box, they also have a window, in which information can be typed. Several examples were already given in section 10.2. The syntax for the input box. function is... 

An introduction to SQL is provided in Chapter 3, but with an emphasis on examples relevant to chemical information rather than business information, which is often used in other books. Chapter 4 discusses some of the RDBMS that are available, namely Oracle, MySQL, and PostgreSQL. All of them use SQL to insert, delete, update, and select data. Chapter 5 shows ways in which client programs, including Web-based applications, are used to connect to the database server. Chapter 6 examines ways in which RDBMS are typically used to handle numerical and textual chemical information using relational tables. An example of using data files from the PubChem project is included. 

The exchange format is a textual file with a Lisp-like syntax. This makes the format easily extendible for local or future needs, while maintaining backwards compatibility with older programs that do not understand these extensions. 

We will assume here that the (non-uniform) dependence graph of the APP has already been extracted from the initial textual specification. In practice, this step can be performed automatically from applicative languages in a relatively simple way, as explained briefly in chapter 6 or from procedural nested loop notations expressed in any standard programming language, with more complex procedures, as discussed in chapters 4 and 5.
