- CUREDIT, CURSET Version 3.5, (C) Copyright 1993 Mike Heilemann
-
- Programmed by Mike Heilemann
-
-
- 1.1
-
- DEFINITION:
-
- CURSOR SET (CURSET.EXE) is a TSR program which takes less than 10K of memory.
- The function of this program is to transform the dull blinking DOS cursor to
- a lively animated one. CURSET is especially usefull on Laptop or computer
- systems with LCDs or similar displays. As many people have found, it is
- very easy to lose the normal underscore cursor. CURSET banishes this problem
- forever!
-
- Curset performs it's magic by dynamically re-mapping one of the standard ASCII
- characters with your predefined animation frames. By cycling through the
- frames many times per second it achieves the illusion of smooth animation.
- (Just like a cartoon!)
-
- There are a few limitations that you need to be aware of when you use curset.
- Fortunately, most computer systems out there today fall outside the bounds of
- these limits. Requires a 286 or better system with an EGA or VGA video adapter
- to run CURSET.
-
- A single ASCII text character is really just a 16 x 8 block of pixels. (8x8
- pixels in 43/50 line mode) Each row of 8 pixels is refered as a SCAN LINE. EGA
- and VGA cards will allow a clever programmer to re-define some or all of these
- characters, and replace them with another pattern. CURSET redefines one of the
- 255 different ASCII characters every second. This character is then used for
- your cursor!
-

-
- COMPATIBILITY:
-
- Hardware/Software Requirements:
-
- - A 286 or better CPU (recommended)
- - EGA or VGA video card and monitor
- - MS-DOS 3.1 or higher.
-
- Software Compatability:
-
-
- 4DOS, NDOS, DRDOS 6.0, DESQVIEW, Stacker 2.0+, QEMM 6.0+, OS/2 2.0 VDM and
- should be compatible with most other software.
-
- CURSET may be loaded high memory with QEMM, 386-MAX, DOS 5.0 & 6.0 EMM386, and
- OS/2 VDM. Other memory managers have not been tested, but I see no reason why
- they would not also work.
-
- Windows sometimes has problems remapping characters. CURSET detects and
- disables itself when Windows 3.0/3.1 is loaded. The problem is that when
- a "windowed" DOS session is switched to full screen mode, the display could be
- garbled.
-
- OS/2 has no such problem, and CURSET works when switching from Windowed to Full
- Screen. Please note that if you do switch from a Full Screen to Windowed DOS
- session, the cursor will be disabled until you switch back.
-
- If you find that a particular application has problems with CURSET, you can
- easily create a batch file to disable CURSET and run the app. The batch file
- can then re-enable CURSET after the program has terminated. Example:
-
- @ECHO OFF
- CURSET /OFF
- PROGNAME.EXE REM This is your bad application...
- CURSET /ON
-
-
- Some programs such as Norton Utilites, PC Tools, and others use the same
- character remapping technique as CURSET to make their programs have more of a
- graphical look and feel. If such programs remap the same ASCII character as
- CURSET (which defaults to 255), you may wish to change the character that CURSET
- uses. Character number 05 should be a good alternative. To load CURSET with an
- alternate remap character, use the following command line:
-
- CURSET /005
-
- Any character from 000 to 255 can be used after the '/'. Please note that you
- can only change the character during initial startup of CURSET. You can NOT
- change the remap character while curset is loaded. To get around this, do
- the following:
-
- CURSET /U <-- Uninstall CURSET
- MODE CO80 <-- Reset video card, and EGA/VGA character set
- CURSET /### <-- Load CURSET with the new remap character
-
-
- 1.3
-
- COMMAND LINE USAGE:
-
- CURSET </###> </C:##> </NOINV> </ON | /OFF> </UNINSTALL> <FILENAME>
-
- Current function of switches:
-
- /### - Set remap character (0-255) Default is 255
- /C:## - Set foreground cursor color from 1 - 15
- /NOINV - Disable inversion of cursor upon detection of a solid block cursor
- /ON - Enable cursor
- /OFF - Disable cursor
- /U - Removes program from memory if possible
- FILENAME - Read in cursor file filename
-
- You can choose a different remap character with the /### command where ###
- is the decimal value (from 0 - 255) of the ASCII character you wish to remap.
-
- Setting the color of the cursor will set the foreground color only. CURSET
- leaves the background color totally alone. If no color is specified, it will
- keep the forground color of whatever character it is on. If a foreground
- color is specified, and it happens to be the same as the background color,
- CURSET will use the old foreground color.
-
- The /NOINV will make it so CURSET's cursor will NOT invert. In this mode it
- will always animate unless it is turned off or hidden by some program. CURSET
- normally inverts the cursor when it is turned into a solid block. Actually
- it inverts it when the cursor is set over 6 scan lines.
-
- If CURSET is unable to uninstall itself, that indicates that some other TSR
- has been loaded after it. If this is the case, CURSET will remain in operation
- IE. the cursor will remain animated. In order to uninstall it you will first
- have to unload all the other TSR programs that have been loaded after CURSET.
- Though you may use the /OFF switch to disable CURSET.
-
- CURSET changes the keyboard repeat rate, so that the timer can keep up with
- the output to the screen. The rate CURSET changes it to is faster than the
- normal repeat rate (17.1 characters per second) as opposed to the normal 10.0
- characters per second). If this rate is changed by another program, in some
- instances the remap character can be left on the screen during scrolling.
-
-
-
- 1.4 DESIGNING YOUR OWN CURSORS
-
-
- FILENAME is the name of the cursor file you wish to use for CURSET's animated
- cursor. The format for such a file is:
-
- 1 BYTE - number of frames from 1 to 10.
- 16 * number of frames BYTES - value of 16 scan line cursor.
- 8 * number of frames BYTES - value of 8 scan line cursor.
-
- Each scan line is made up of a byte, with each bit determining if the
- corresponding pixel is on or off. For example, here is one frame of an 8 scan
- line cursor:
-
- *______* 81 Hex 129 Dec
- *__**__* 99 Hex 153 Dec
- **_**_** DA Hex 218 Dec
- _**__**_ 66 Hex 102 Dec
- _**__**_ 66 Hex 102 Dec
- **_**_** DA Hex 218 Dec
- *__**__* 99 Hex 153 Dec
- *______* 81 Hex 129 Dec
-
- The file must contain the numeric values, not an ASCII value. Remember that you
- also need to create a 16 and an 8 scan line cursor for the cursor to show up
- properly in all text modes.
-
- This conversion process is pretty long and tedious for making cursors, so when
- you REGISTER your copy, you will receive CUREDIT, which allows you to make
- your own cursors with minimal effort, using the keyboard or mouse. It also
- allows you to edit cursors, and see the animation sequence.
-
-
-
- 1.5
-
- HOW IT WORKS:
-
- CURSET works by remapping a video character constantly cycling through the
- animation sequence. The remappable character can be defined by the user with
- the /### switch upon initial startup (see the above command line switches).
- This may cause a slight problem with some applications that display special
- characters. If they display the character you are remapping on the screen,
- it will be animated instead of the character they ment to display. The default
- remap character is 255 which is a blank unused character, so the only problems
- you should see are in programs which use and remap this character, in HEX
- dumps, or executables and the like.
-
- CURSET also gets requests to change the cursor and handles them in its own way.
- No matter what request to change the cursor comes in, we disable the cursor,
- but we do handle 3 different cases: turning the cursor off, turning the cursor
- on, and making the cursor a full or almost full block. The only difference
- you are likely to see is when the cursor is a block, in this case, we invert
- our animating cursor. This is usefull when in applications that use a block
- cursor to indicate a special cursor mode, such as insert.

- CURSOR EDIT (CUREDIT.EXE) NOTES:
-
- CUREDIT will be sent to you when you register your copy of CURSET. It allows
- you to make custom cursors of your own design quickly and easlily. Mouse and
- Keyboard are both supported. Frame copying, frame shifting, in editor
- animation, 16 and 8 scan line cursor editing on the same screen are all part
- of CUREDIT!. It will also detect if curset is loaded, and disable the curset
- cursor, which makes it easier to see what you are editing. You can edit a
- cursor and save it out with a new name, allowing for veriations on cursors.
- Scrolling cursors are now a snap with the new commands to move frames up,
- down, left and right. More documentation will be provided on the disk after
- registration of CURSET. Please fill out and send in the registration form if
- you are interested.
-
-
- <A>nimate goes through 6 repititions of the animation sequence. It also
- cycles the top remap characters.
-
- <C>opy makes a copy of the frame and places it in the next frame. Upon
- copying a frame, will move you to that frame if you are currently on the last
- frame.
-
- <U>p rolls the current frame up one scan line, moving the image up.
-
- <D>own rolls the current frame down one scan line, moving the image down.
-
- <L>eft rolls the current frame to the right.
-
- <R>ight rolls the current frame to the right.
-
- <X> Clears current frame.
-
- The HOME key puts you at the top left of whatever cursor you are working on
-
- The END key places you at the lower right.
-
- All cursor keys, will wrap to the opposite side of the screen.
-
- Page up and down will also wrap from first to last, or last to first.
-
- <TAB> moves you from the 16 line to the 8 line cursor and vice versa.
