Standard Windows Commands

Beyond the standard Windows commands, ACID menu shortcuts are identified to the right of the specific command. For example, all of the various windows in ACID can be instantly displayed or hidden by using the commands on the View menu or by using the associated keyboard shortcuts. 

This list could be topped by the standard Windows commands Ctrl +Z and Ctrl+Y (Undo and Redo) as well as Ctrl+C (Copy), Ctrl+X (Cut), and Ctrl + V (Paste). Of course holding the Ctrl key (or Shift key) while selecting events allows you to select multiple events. And don t forget the Windows motto— Save early, save often Ctrl+S. 

The loading of a configuration file (cfg files) is done using the Load from file... command in the File pull-down menu. In the Check its this operation is described by the short hand notation File Experiment setup Load from file. A left-hand mouse button click on the command field opens a standard Windows file list box. In this file list box it is possible to select a specific cfg file either directly from the keyboard or by using the mouse it is also possible to change the directory and/or disk drive if necessary. 

For a set of simulated data it would be desirable to be able to process all the data using the same processing parameters, such as zero filling or window function. It is possible to define a limited number of processing parameters in NMR-SIM and have these parameters transferred directly to ID WIN-NMR or 2D WIN-NMR with the simulated experimental data. It is then possible to process the simulated data utilizing the parameters defined in NMR-SIM using all the standard processing commands in ID WIN-NMR and 2D WIN-NMR. 

The Edit pull-down menu lists all features for the information input and functions dealing with chemical structure editing as well as the standard Windows functions like Copy and Paste. However, only three OPUS commands are active in the demo version (see Fig. 7.1). 

Menu and Tbolbar— These are standard Windows features that you are probably comfortable using. The menus contain very nearly all of the commands that control AQD. The toolbar contains a smaller subset of more frequently used commands and can be customized to display your choice of buttons. 

ACID makes extensive use of shortcuts to speed up commands. Many of these shortcuts follow standard Windows conventions—for example, the Copy command can be quickly executed by pressing Ctrl + C on your keyboard simultaneously. Likewise, a Save command may be executed by pressing Ctrl + S. 

Sound Shaper is a GUI for the CDP sound transformation toolkit, developed by Robert Fraser. This comprehensive piece of work is written in Delphi and is available for the IBM PC-compatible Windows platforms. It sits on top of and transparently makes use of the standard CDP command line set of programs, so it will work immediately with any current Release 4 version of the CDP System. 

To implement such a rule we need to do some arithmetics to determine the position of the limits of the tolerance window. PROLOG is not an arithmetic language. Thus handling of numerical calculations is somewhat clumsy. The standard arithmetic operators are part of the language. However, they are interpreted as specifying a relation between numbers rather than as commands to perform a calculation. In particular, the operator = signifies equality, but does not trigger the evaluation of an arithmetic expression. 

By default Matlab will be installed in the directory C matlabrxx on your PC, where xx relates to the edition of the package. You can choose to install elsewhere but at first it is best to stick to the standard directories, which we will assume below. You need some knowledge of DOS directory structure to use the directory commands within Matlab. According to particular combinations of versions of Windows and Matlab there is some flexibility, but keeping to the commands below is safe for the first time user. 

Any real understanding of the success of DOS after 1987 requires knowledge of Windows. In the early years of its existence, Microsoft s DOS gained great acceptance and became a standard as a PC operating system. Even so, as computers became more powerful and programs more complex, the limitations of the DOS command-line interface were becoming apparent (as well as the aforementioned conventional memory limitation). 

In general, Windows 98 uses more text-based commands than Windows 2000, and a number of standard commands are stored in the Windows 98 command directory. This can be found in whichever directory (usually Windows) that Windows 98 is installed into. See Table 12.1 for a list of Windows text commands, some of which are available only in Windows 98, while others are available in Windows 2000 as well. 

After the command selection the window mode will change and the functionality of the button panel will be modified to incorporate any command specific buttons. It is also possible that some of the standard buttons will be deactivated. 

The names STDIN and STDOUT are derived from standard input and standard output, an idea popularized by the UNIX operating system. Standard input and standard output are abstract files from which a script can accept input and send output, respectively. When a script is first launched, standard input corresponds to the keyboard and standard output corresponds to the computer screen. On Windows and UNIX systems, standard output appears in the command interpreter window. On Macs, the output appears in a small scrolling window that MacPerl creates specifically for this pmpose. When a Perl script is laimched, the user has the option of changing where standard input and output come from and go to. The user can also arrange for the standard output of one script to be sent to the standard input of another script in assembly-line fashion. This is actually a very powerful facility, but one that is beyond the scope of this chapter. 

Many of the menu and toolbar items are standard features of any good Windows application. The main menus at the top of the program are the most comprehensive list of available commands in ACID. 

One idea was to offer the macro functionality as an extra input modality for everybody. For this reason we implemented a software prototype which is able to recognize a list of gestures and trigger a corresponding command. We used the WM APPCOMMAND of the Windows operating system to realize an open document, save document and close document function which works with standard...
