- A Demonstration of Windows for C
-
- The text available in this message window can be expanded by pressing
- function key F6.
-
- The keys on the cursor pad have been programmed to allow you to move the
- windows over the text.
-
- The cursor keys move the cursor. When the cursor reaches the edge of
- a window, additional movements cause the window to move over the file,
- until the edges of the file are reached. Horizontal as well as vertical
- scrolling is available.
-
- Cursor arrow-keys move one space in the direction of the arrow;
- except that left and right arrows cause horizontal scrolling of five
- spaces when cursor is at screen edge.
-
- Ctrl-left and ctrl-right arrow-keys move the cursor 5 spaces.
- (Page-left and page_right in the terminal environment).
-
- Ctrl-PgUp and ctrl-PgDn cursor keys move the cursor up and down
- 5 spaces in the DOS environment.
-
- PgUp moves the window up the text one window-length.
-
- PgDn moves the window down the text one window-length.
-
- Home moves the window and cursor to the beginning of the file.
-
- End moves the window and cursor to the last row of the file.
-
- For this demonstration, three text files are available for viewing in six
- windows.
-
- File 1 contains the source code for the demonstration program that you are
- presently viewing.
-
- File 2 contains a summary description of Windows for C.
-
- File 3 is the text file that you are now reading.
-
- Different combinations of windows and files can be activated by
- pressing function keys F1 through F6. F10 will exit the demonstration.
-
- F1 and F2 place files 1 and 2 in overlapping vertical windows. The last
- window activated will lie on top.
-
- F3 and F4 place files 1 and 2 in non-overlapping horizontal windows.
-
- F5 makes the bottom "message window" active.
-
- F6 is a very important key. It places the presently active file
- in a large window at the top of the screen. Thus to view any one of
- the three files in the large window, first press the function key that
- makes a smaller window containing that file active, then press F6. For
- example, F1 or F3 followed by F6 will place file 1 in the large window;
- F5 followed by F6 will place the message text you are now reading in
- the large window.
-
- F10 exits the demonstration.
-
-
- To experience the convenience and power of Windows of C use the various
- function keys to move the files into different windows. Use the cursor
- keys to move the windows over the files.
-
- When you are done, press F10 to exit the program.
