Window Functions You can browse two windows of text simultaneously. To open another window of text or resize an existing window, use the Windows keyset. When viewing two windows of text, you can set the following options independently for each window using the Set Options and Print Text functions: * Display Line Numbers * Forward/Back Scroll Size * Left/Right Scroll Size * Lines Per Page * Output Device * Print Line Numbers * Print Header Lines * Line Range The remaining HP Browse options are global; that is, they apply to both of the windows even if the windows contain different files. The global options are listed below. * Highlight Match * Ignore Case * Pattern-Matching Chars * Function Keys * File Path * Search Pattern Also, the Exit function always applies to both windows. The remainder of this section describes the functions you can use to manage windows in HP Browse. Open Window The Open Window function splits the text window horizontally into two text windows. The split occurs at the line where the cursor is located on the screen. There are three conditions under which you cannot use the Open Window function key: * If the cursor is in the status area. * If HP Browse is already displaying two windows. * If the resulting window would have less than one line of text. In all three of these cases, HP Browse displays an error message and the Open Window function is not performed. Close Window Use the Close Window function to close the text window that the cursor is positioned in. When you press the Close Window function key, the remaining window expands to fill the space occupied by the closed window. If you are browsing two different files, HP Browse hides the current window when you press Close Window. With one window hidden, you can have a full screen display and switch between files by pressing the Close Window function key. See Chapter 2, "Managing Windows" for more information. To redisplay the window you have just closed, use the Open Window function. This will create a new window and display text from the previously closed window with its corresponding window options. Size Window You can change the size of the current window by using the Size Window function. The new size of the current window (in lines) is specified by the count parameter. If you do not specify a count, the current window will be enlarged by one line and the other window will be reduced by one line. The size of the other window will always be adjusted to fill the remainder of the screen. Switch Window In HP Browse you can manipulate two windows independently by moving the cursor into either window before executing a function. To move a cursor from one open window to another, press the Switch Window function key or simply use the cursor movement arrows on your keyboard to position the cursor into the other window. If a window is hidden, the Switch Window function will display the hidden window and hide the previously displayed window. Refresh Screen The Refresh Screen function redisplays the current text window (or windows). Two possible reasons for refreshing your screen are if you pressed a key that manipulates the terminal screen (like Clear Display) or if some data communications interference has produced garbled characters on the screen. When you press the Refresh Screen function key or the * character, HP Browse redisplays the entire screen.
