Examples include the calculator and phone book. Services are general- purpose modules containing functions used by several tasks or services. You can activate tasks, while tasks or services activate other services. EXE file.
The size of the SK. EXE file you generate will therefore depend upon the number of applications installed. Figure 2 shows the development of a module. Hie application program interface processor and assembler translate the description into a module header containing necessary data structures. Ihis module is then linked together with the task object and API library , making a ready-to-install module. The resulting header file contains information describing the module entry points used by the kernel.
Linking requires the API library that contains the access routines for the kernel and services. Thsks normally display primary information in a main window.
The SideKick Plus time planner, for example, has four windows see photo 1. In the photo, the calendar view is open with the schedule view on top. See the insert card following page 80 for details.
See page 4. The programmer can decide whether or not the user should have control over the size of a window in some cases. If the user had selected the address entry, the menu would have disappeared and an address window would have opened.
No longer do software vendors dictate the form or style of the menus or keys to activate a command. Photo 2 shows how to do this. The bar is on the Speed entry and we.

The menu system is more than just a selection tool; you can use it to enter and change values. Full Memory Management As outlined earlier, the kernel supports memory management. Its two different uses are to swap tasks and services and to give tasks access to dynamic memory.
The task manager controls the overlaying of task and services, activates tasks, and acts as a channel for service requests from the API. Running an executable file prompts the task manager to load the necessary tasks and services into memory and swap files.
When a request to execute a service or task occurs, the task manager checks to see if the module is in memory. If it is not, the task manager loads it from the swap file. If you do not require the task for a temporary period, it can be released and swapped to disk. If you must access the memory block at a later time, the task can reclaim memory and be swapped back into memory if necessary.
After use, the memory block is freed. All large uninitialized data structures used by tasks should be allocated in dynamic memory. That way, they can be swapped out when the task becomes inactive, thereby freeing memory. Because a particular task can work with more than one dynamic memory block and each block is expandable to 64K bytes, each task can easily work with large amounts of data. Listing 1 illustrates the use of dynamic memory. The code shows part of a task.
The procedure OpenProc is called when the task activates the first time. OpenProc opens a window. The procedure EntryProc contains the mainloop within the task, which polls the ReadChar routine for a keystroke.
The CloseProc procedure frees the buffer. The Editor The editor is a useful service module. In addition to its use by the notepad task to provide up to nine separate notepads, it has many other practical purposes. It can attach notes to appointments in the time planner.
It can attach notes to phone book entries and edit communication programs executed when dialing remote computer systems. The tape is edited and saved as a text file. Once it receives a dynamic-memory data segment or a filename, it executes. Running out of memory is not a problem in cases where multiple editor windows are open at the same time. The File-Management System The. Each time you specify a filename containing wild cards, the file window opens and lets you brows5 through your directories.
You can then either select a file or press Escape. The file manager is both a service and a task. Data Communication Data communication plays a major role in the SideKick Plus phone book and munications tasks.
Among the other available services is a modem manager that supports dialing from a variety of modems. You can dynamically reconfigure the port on the fly i.
A file-transfer protocol manager enables the task to transmit or receive symbolic or binary files, optionally under protDcol control e. Coding is a waste of time. Why should you have to work hard just to get dBASE to do what you want? Design any kind of screen using the built-in Form Editor.

Use them in any application. Linked Files: Link up to 5 databases together on one form using relations. Advanced Form Editor: Specifically designed for building database forms. The one which lets you design reports in seconds simply by drawing them on the screen without any programming.
No longer are you limited to one line per record. No longer are you limited to one database per report. However, a relatively unknown type of database, called the network-model DBMS, has significant capabilities over the others. The DBMS network refers to interconnected data records. The first users of microcomputers were not programmers; therefore, a need existed for easy-to-use DBMS products. Now, more network DBMS products are showing up and this is a boon for serious software developers.
Finally they have a range of high-performance network- model DBMSs to choose from that are suitable for developing major applications. Relations can be linked together on the basis of a common field. Suppose you have a customer relation and an invoice relation laid out like the one in table 1. NE , Bellevue, WA If a program Were processing the invoice relation row by row, it could look up the customer in the customer relation as needed in order to produce a report like that in table 2.
Another program could process the customer rows and find all the associated invoices for each. The relational DBMS depetids on indexes for its speed. The index allows quick access to each record. The main added feature is the data dictionary built into the file structure. The main attraction is that you can change the system easily. You can add and delete fields; you can also establish new relationships merely by associating common key fields in different tables.
For a major accounting application, you would need as many as 50 data files and over index files, and you would have to include common key fields in all related records. If you changed the value of a key field in one relation, you would have to be certain to make the same change in all of the relations you wanted to connect.
Consider the common situation of an invoice header record and its associated detail-line items. Typically, items are numbered 10, 20, 30, and so on. You can insert nine more line items before you fill the slots between 10 and 20, but then you have a problem. Now you will see how the network model gets Table 1; A customer relation and its invoice relation.
The difference is in the way records are linked together. The Cust field no longer needs to remain in the invoice record. Each invoice can have line items attached through another set.
Thus, the invoice line-item records can be linked to their header record in the same order in which they were entered.
You can insert new details anywhere. With one of these large network-model databases, you can define simultaneous access to all records in all sort and selection orders. If you do not know your reporting needs from the start, or if you must change the system often, the relational model makes more sense. When the end user is satisfied with the screens and system flow, the developer recodes using a network-model DBMS.

The real schema would be comprehensible only to telephone engineers. Central to the schema is the extension record. An extension rings on a station at a specified line number.
Some records are connected with several sets. Take the extension number, for instance. This would be difficult in a relational system because the extension number would occur in over 20 different records. The network model solves that problem because the extension Phone systems evolve as companies constantly change, therefore a configuration program must be flexible. Note that all the sets shown in figure 4 determine two-way relationships.
Including these extra keys would further increase redundancy, making it harder to make changes to the data. Other Network-Model Applications The telephone application is a medium- complexity network example.

The fact that a particular program boasts tremendous sales figures does not mean that it is the best in its category or even especially outstanding. Likewise, an excellent product might cause barely a ripple in the marketplace.
Some software is ahead of its time. Other programs are too similar to existing products to be noticed, even if they incorporate significant improvements. And a few products simply baffle reviewers. On average, I receive about 30 software products a month, and I write about four of them.

Both are excellent products that you might not hear about from your local software dealer. You can install any or all of the tools into the framework. The result is a pop-up utility that covers only the functions you need.
Although some of the more straightforward tools, such as the statistics calculator, require only one screen, many of the modules use a long series of linked screens. A good example is the personal financial statement, which uses separate schedules for different sorts of assets and liabilities.
The program gives you a data-entry screen of 20 lines a status line at the top and a function-key menu at the bottom occupy the rest of the display.
Each line is divided into three areas. Think of it as the equivalent of the tape from a printing calculator. The third area is simply a space for remarks or line labels. You can use It Figures to perform any top-down computation.
