Normally, the mouse cursor is shaped like a block, and is hard to control. With Precise Point this block is transformed into a smoth moving graphics style pointer. Precise Point remains in memory until the computer is reset or turned off. Almost all text mode mousable applications make use of the new mouse cursor. Graphics applications are not affected. REQUIREMENTS ─────────────────────────────────────────────────────────────────────────── ■ IBM PC XT, AT or compatible computer ■ DOS 3.0 or higher ■ EGA or VGA video adapter ■ Any mouse or pointing device and driver software examples of driver software are named: mouse.sys, mouse.com, gmouse.com. Refer to your computer manual for more information. ■ Precise Point will take up approximately 6500 bytes of core memory when loaded. This memory can be saved by loading in high memory (see INSTALLATION) INSTALLATION ─────────────────────────────────────────────────────────────────────────── To load Precise Point, type PP at the DOS prompt. It will remain in memory until the computer is reset or turned off. To automatically load PP each time your computer is started, add it to the autoexec.bat file. The Auto Load button in PPCONFIG can perform this installation step for you. PP may be loaded in high memory using DOS 5.0, DR Dos, or a memory manager such as QEMM/386 or 386 to the Max. This will eliminate the 6k memory overhead required by PP.

Words in brackets [] are optional. /? Displays a brief summary of options that can be used from the DOS command line. The status line indicates whether PP is loaded in memory and activated. /H Invokes a comprehensive interactive help system. Allows the user to select and view help topics. Help on PP and PPCONFIG is available. /U Restores the block mouse cursor and removes PP from memory, if it was the last application loaded. /E, /D Activates or deactivates PP, if it was previously loaded. PP continues to remain in memory. When running under DESQview, PP is automatically deactivated. /EGA[43] /EGA sets 25 line EGA mode, using 8x14 matrix character set. /EGA43 sets 43 line EGA mode, using 8x8 matrix character set. /VGA[50] /VGA sets 25 line VGA mode, using 8x16 matrix character set. /VGA50 sets 50 line EGA mode, using 8x8 matrix character set. Both options cause the hardware video font to be loaded. /R, /S These fonts eliminate the VGA character distortion problem. It is valid in VGA 25 line mode only. The font reverts to the default hardware font when the video mode changes.

This annoying pause is most noticeable when applications are started. The fast mouse option uses an alternate method of resetting the driver which is instantaneous. PP automatically determines if your mouse driver is capable of this feature at install time. Older drivers, such as Genius 9.01 and Microsoft 6.24 do not support this feature. Certain rare driver/software combinations do not work properly with the fast mouse option. In such cases, the /N manual override should be used. Normally, these switches are not necessary. > nul Prevents messages from being displayed on the screen. This must be the last option on the command line. (ie: PP /S > NUL) Precise Point 1.00 Page: 7 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ COMMAND LINE EXAMPLES ─────────────────────────────────────────────────────────────────────────── C:> PP Precise Point is loaded in memory and settings from the configuration file PP.INI (if present) are used. ...........................................................................

The .ini file extension is optional. While loading, PP uses the config file PP.INI if present and if no other config file is specified. Files are searched in the following manner: ■ explicit path if specified ex: pp c:\mouse\face.ini ■ current directory ■ pathname from which PP was executed ex: c:\mouse\pp face.ini looks for c:\mouse\face.ini Advanced users may wish to add or remove certain sections using a standard text editor. This is especially useful in creating independent sacrifice maps, or bitmap shapes. Precise Point 1.00 Page: 9 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ FREQUENTLY ASKED QUESTIONS ─────────────────────────────────────────────────────────────────────────── Question: The PP cursor appear on more than one part of the screen. Cause: Occurs when the application is using a character that is part of PP's sacrifice map. Solution: Modify PP's Sacrifice Map using PPCONFIG. There are also several config (.ini) files which contain custom sacrifice maps. For example, the file FOXPRO.INI has a specially defined sacrifice map to avoid conflicts with the FoxPro Database. ........................................................................... Question: When I move the PP cursor over certain characters (ex: 0, A, M, w) their right edge grows thick. Cause: This problem only occurs in VGA 25 line mode. The hardware design of the VGA does not allow programmers to precisely control the 9th pixel of each character. Solution: Use another character font. Two specially designed fonts are built into PP and can be activated by the /S and /R command line switches. Fonts can also be activated from PPCONFIG using the Default Font button. Example: C:> PP /S loads the Sans Serif character font ........................................................................... Question: The PP cursor leaves droppings when I drag a window or move a pull-down menu, how do I solve this? Cause: The application is designed to work with a one cell mouse cursor. PP's cursor may occupy as many as nine adjacent cells. Solution: Choose a smaller mouse bitmap (ex: small.ini) whose size is less than 8x14 pixels. Many Borland applications have a useful screen "refresh" menu option which also fixes this problem. Incidentally, the Microsoft 8.20 driver's medium and large mouse cursors also exhibit this problem. This is an easily fixable problem for software developers. Precise Point 1.00 Page: 10 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Question: Why does the color of the PP cursor change as I move over different parts of the screen? Cause: PP uses the foreground color of the character underneath the mouse cursor. Solution: Due to hardware limitations, it is not possible to superimpose a totally different color mouse cursor in text mode. If your program allows the color scheme to be changed, try choosing similar foreground colors. The background color does not affect the color of the PP cursor. ........................................................................... Question: I see a block mouse cursor even after PP is loaded. Causes: The application may be using the hardware cursor (example: CompuShow 8.4) PP only affects the 'software' mouse cursor. You may be running DESQview. The current version of PP does not support the DESQview multitasker. Some applications, such as WordPerfect 5.x, XTreeGold 2.5, Telemate, and Quattro Pro 4.0 simulate their own mouse cursor instead of using the one provided by the mouse driver. Solution: None. Software developers are encouraged to utilize the software mouse cursor and other services from int33h. See also: SMD Programming Kit from the Help Index. ........................................................................... Question: In a windowed DOS session in Windows, or OS/2. I see squiggly characters in place of the mouse cursor. Cause: PP works rather intimately with the video system, and many of the video tricks it uses are not possible in graphics modes. Solution: Switch to full screen mode. Preferably, close the window and start a new full screen DOS window. Both OS/2 2.0 and Windows 3.1 allow you to use their own graphical mouse cursors in DOS text applications, so there is no need to use PP if you are using a windowed DOS session. Precise Point 1.00 Page: 11 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ERROR MESSAGES ─────────────────────────────────────────────────────────────────────────── The following messages may be displayed at the DOS prompt: 1: Cannot run under DESQview PP does not run properly under the DESQview multitasker. It will not installed if DESQview is detected. If DV is run after PP is installed, it will disable itself. 2: Installation failed PP could not be installed successfully. Your mouse driver is probably too old. Upgrade to a new mouse driver. 3: Precise Point already installed (PP /? for help) You tried to install PP when it is already installed in memory. 4: Precise Point not installed, option invalid You tried to use a command line option, such as /E, that requires PP to be installed in memory. The following utility options /EGA /VGA /S /R can be used without PP being installed. 5: Precise Point unloaded from memory This message informs you that PP has been successfully unloaded from memory. 6: Mouse driver not installed The regular mouse driver (mouse.com or mouse.sys) must be loaded before PP is installed. If you are running PP from your autoexec.bat, place PP line appears at the bottom of the file. 7: Cannot remove Precise Point from memory You may have another program installed in memory after PP. The system may be unstable at this point, you may want to reboot. 8: This program requires an EGA or VGA video card You must have an EGA or VGA compatible card. 9: This option only works on VGA cards Options /VGA /S /R require that you have a VGA video card. 10: Configuration File not found The configuration file you have specified cannot be found. If you forget to use a slash (/) or dash (-) in front of a command line option, you may also get this message. 11: Unrecognized option (PP /? for help) You have used an invalid command line option. For a list of options, see the help topic "PP Command Line Options".

Blue buttons perform general actions which affect the entire program. Green buttons are used to manipulate the active bitmap at the center of the screen. The two white buttons are associated with the sacrifice map. And the orange button chooses between various screen fonts. Buttons ─────── UNDO Allows you to revert to the way things were just before the last action you took. LOAD/SAVE CONFIG Allows you to save your work to disk in a configuration file. The bitmap, sacrifice map, and sensitivity settings are saved. You may also load any previously-saved .ini file. TOGGLE BITMAP Switches between the cursor (foreground) or screen (background) bitmaps for editing purposes. DEFAULT FONT/SAN SERIF/ROMAN Switches between the Default (system), San Serif (custom), or Roman (custom) character font sets. AUTO LOAD Adds PP to your autoexec.bat file for automatic loading. A backup file is saved as autoexec.bak. HOTSPOT Allows you to alter the center point of the bitmap. The hotspot location appears in yellow spot in the bitmap area. DEFAULT SACMAP Lets you select from one of three predefined Sacrifice Maps which Sacrifice Map you want to use. TEST BITMAP Allows you to test the Hotspot, and to see the cursor (foreground), and its screen bitmap (background). Precise Point 1.00 Page: 13 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ DUPLICATE Replaces the visible bitmap with the hidden bitmap. For example, if you are editing the screen bitmap the cursor bitmap will be copied over, or vice-versa. ASCII VALUES Toggles between viewing entries on the Sacrifice Map as values or as their character representation. FLIP X/FLIP Y Affects the currently displayed bitmap as follows: ┌───────────┐ ┌───────────┐ ┌───────────┐ │ ■ │ │ ■■ │ │ ■ │ │ ■■■ │ │ ■ ■■ │ │ ■■■ │ │ ■■■■■ │ │ ■■■■■■ │ │ ■■■■■ │ │ ■■■■■■ │ │ ■■■■■ │ │ ■■■■■■ │ │ ■ ■■ │ │ ■■■ │ │ ■■ ■ │ │ ■■ │ │ ■ │ │ ■■ │ └───────────┘ └───────────┘ └───────────┘ Original Flip Y Flip X INVERT/GROW Affects the currently displayed bitmap as follows: ┌───────────┐ ┌───────────┐ ┌───────────┐ │ │ │■■■■■■■■■■■│ │ │ │ │ │■■■■■■■■■■■│ │ ■■ │ │ ■■ │ │■■■■ ■■■■■│ │ ■■■■ │ │ │ │■■■■■■■■■■■│ │ ■■ │ │ │ │■■■■■■■■■■■│ │ │ └───────────┘ └───────────┘ └───────────┘ Original Invert Grow Precise Point 1.00 Page: 14 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Bitmap Editing ────────────── The bitmap editing area in the center of the screen, allows you to create or edit the shape of the mouse cursor. The 'screen bitmap' determines the background area to be erased. The 'cursor bitmap' is then superimposed on top of the same area in the foreground color. The Toggle Bitmap button selects between these two maps. The 'screen bitmap' is generally used to create a border around the 'cursor bitmap'. For this reason, the former should be slightly larger in size than the latter. A typical sequence of steps in creating a mouse cursor are: ■ Draw the cursor bitmap ■ Press Toggle Bitmap \ screen bitmap is ■ Press Duplicate > generated automatically ■ Press Grow / by these steps ■ Set the Hotspot ■ Use Arrow keys to shift bitmap if necessary The four arrow keys shift the entire bitmap in the indicated direction. For optimization purposes, the bitmap should be shifted to the upper left corner of the screen. Sacrifice Map ───────────── Up to 9 characters, from a collection of 256*, are redefined for use with the mouse cursor. These characters cannot be used by other applications -- they must be 'sacrificed.' By default, PP chooses 9 least used characters for the sacrifice map. In rare cases, an application uses a character that is in the sacrifice map. When this occurs, the mouse cursor appears to be in more than one area of the screen. To remedy this, a new character must be selected from the ascii table. ┌───┬───┬───┐ │215│216│208│ Items in the map may be viewed as numeric values ├───┼───┼───┤ or as character by using the Ascii Values button. │210│212│213│ ├───┼───┼───┤ There are several configuration files which contain │211│198│199│ predefined maps for some applications. └───┴───┴───┘ * Characters 32 to 126 represent ordinary text patterns and should not be used in the sacrifice map.

It contains a table of the 256 available characters and their corresponding values. Gray bars indicate a currently chosen sacmap value. The black bar indicates the cursor-select position. Double click on the black bar to select the character. Press the right mouse button to cancel the window. ┌─────────────┐ │ ... │ │ 130 VGA │ <- 'VGA' indicates character is │ 131 --- │ suitable for VGA 25 line mode. │ 132 --- │ Choosing a '---' designated │ 134 VGA │ character may cause vertical │ ... │ lines in the mouse cursor. └─────────────┘ Sensitivity ─────────── Certain combinations of mouse drivers, mice, and operating systems may affect the sensitivity of the mouse while PP is activated. The yellow bars allow you adjust the horizontal and vertical sensitivity. These settings are saved in configuration files. To automatically load sensitivity settings each time PP is loaded, save the configuration file as "PP.INI" Under OS/2, the sensitivity controls available under the operating system must be used. VGA Considerations ────────────────── The VGA 25 line text mode is organized into character cells arranged in a 9x16 matrix. The VGA was designed such the 9th column in each cell cannot be directly controlled. This complicates matters somewhat and affects PP in two ways: Visual Side Effect: When the mouse cursor is moved over certain characters (ex: 0, M), their right edges grows thick. This can be remedied by using a new screen font. See also /S, /R, and Command Line Options. Choosing Sacrifice Map Characters: When choosing new sacrifice map characters, you are limited to those characters which are designated as 'VGA' on the ascii table. Selecting a '---' character has the effect of disabling the 9th column, and results in vertical lines in the mouse cursor.

SMD libraries provide the functionality of PP in embedded form. They are compatible with C (Borland and Microsoft), Turbo Pascal, and assembly language. C and assembly source code for the libraries, PP, PPCONFIG, and related tools is provided. Alternatively, the PP TSR can be accessed from any language via SMD Interrupt Calls.
