- Solid Cursor (SOLIDCUR.COM)
-
-
-
- 0. NOTE AT THE BEGINNING
-
-
- This program will work with some computers. And with some, it
- won't.
-
-
-
- 1. GENERAL
-
-
- Solid Cursor creates a large, non-blinking cursor in place of the
- normal IBM-cursor. Solid Cursor is a memory resident program.
-
-
-
- 2. FUNCTIONING
-
-
- Solid Cursor blanks the ordinary blinking cursor (if it is allowed
- by the computer's hardware), and creates a large, non-blinking block
- image in place of the ordinary cursor. Color of the block image is
- always reverse compared to the overall color at that location.
-
-
-
- 3. EQUIPMENT REQUIREMENTS
-
-
- The Solid Cursor Program requires certain features in the computer
- hardware. The program also requires some features in EGA or VGA
- hardware, if installed in the computer. Some computers will meet
- these requirements and some won't. A "compatibility" simply isn't
- enough, the only way to see is to experiment with the program.
-
- In addition, the program requires that the computer is booted with
- ANSI.SYS.
-
- Program requires DOS 2.0 or above. Program is active with DOS modes
- 0, 1, 2, 3 and 7, that is to say with text modes. Program switches
- automatically off if the computer is changed to graphics mode.
-
-
-
- 4. TESTING
-
-
- When testing the program for the first time, please follow these
- steps:
-
-
- 1) At worst case, you may have to reboot your computer in
- order to continue. Please be prepared for this.
-
- 2) Give the CLS command at DOS prompt. This clears the
- display, and the cursor is moved close to the upper left
- corner.
-
- 3) Give SOLIDCUR command at DOS prompt. Do not give any
- parameters on command line. This installs the Solid
- Cursor Program resident in memory.
-
- 4) Now, a solid non-blinking block image should be seen at
- the cursor location. Height of the image should be from
- top to bottom of the text line, and color should be
- reverse compared to the overall color. For example, if
- you are using white characters on black background, you
- should now have white color inside the block image.
-
- 5) If your display got confused or if something else happened
- with your cursor, then this program will not function with
- your computer - sorry for that. Please check however that
- you gave the SOLIDCUR command without any parameters.
-
- 6) If the cursor image is now located in wrong position, then
- your computer is not strictly following IBM/DOS display
- standards, or some other program is conflicting. Solid
- Cursor controls the block image through hardware directly,
- and it will fail if your computer differs from standard.
-
- 7) If your computer displays what is said in 4), then go on
- with experimenting. Stay in DOS prompt and give some
- command which makes up more text in the display. For
- example, give the DIR command. Keep watching the display
- when your computer displays the directory listing. Keep
- giving the DIR command so that the display becomes full
- and scrolling begins. Watch the display when it is
- scrolling.
-
- 8) If the display did not behave correctly when scrolling
- started, then most probably your computer is not booted
- with ANSI.SYS. Reboot it with ANSI.SYS. In addition,
- different versions of ANSI.SYS may behave differently.
- Try some other version.
-
- Solid Cursor may behave correctly when used with
- application programs, even if it fails at DOS prompt.
-
- 9) If everything is correctly at 7), then try different
- colors and other than 25/80 displays, if you are using
- such ones.
-
- 10) Color of the non-blinking cursor image should be the same
- as the character color at that location. However, the
- cursor image color should always be low-intensity. If a
- character is located inside the cursor, the character
- color should be same as the background color, but always
- in high-intensity.
-
- Note that the cursor color is always low-intensity. For
- example, if you are using high-intensity yellow as
- character color, then the corresponding low-intensity
- color is brown, and the cursor should be low-intensity
- brown.
-
- 11) If the colors are not as said above or if other than 25/80
- displays will not work, then your display adapter is not
- following IBM/DOS standards, or some other program is
- conflicting. Solid Cursor will fail in such cases.
-
- 12) Hope everything is still working fine at this point. Then
- you may go into real work and see how it feels to use
- Solid Cursor.
-
-
-
- 5. USING THE PROGRAM
-
-
- Solid Cursor Program installs itself resident, when it is invoked
- with SOLIDCUR command. No parameters are allowed on the command
- line when installing the program resident.
-
- When the program is resident in memory, you can switch it off with
- command SOLIDCUR OFF. By the same way, you can switch it active
- again with command SOLIDCUR ON. These commands do not remove the
- program from memory, they only switch it non-active or active. You
- can issue the commands any time you want, they will not confuse the
- program chain in the computer memory.
-
- It is recommended that Solid Cursor is the last one of your resident
- programs. For example, it is recommended to put Solid Cursor last
- in your AUTOEXEC.BAT.
-
- Do not install Solid Cursor resident more than once. Otherwise your
- computer will slow down, and you will not be able to give ON/OFF
- commands to the program. If the program is the last one of your
- residents, you will not be able to install multiple copies in
- memory.
-
-
-
- 6. SLOW-DOWN AND INTERFERENCES
-
-
- Solid Cursor will S-L-O-W D-O-W-N your computer. Slowing will
- happen always when DOS or some application program controls your
- display through BIOS interrupt 10H. Slowing will not happen in
- other cases.
-
- You can check the slowing for example when you watch the display
- during DIR listing. Switch SOLIDCUR OFF and SOLIDCUR ON and watch
- the speed of the DIR listing in both cases. Slowing may be distinct
- with 8088 computers, but with faster machines it is usually not
- confusing.
-
-
- NOTE! Slowing may interference with some application
- programs. If you sometimes notice some unusual, try
- switching SOLIDCUR OFF and see if slowing was the fault.
-
-
- Solid Cursor may also cause interferences on the display.
- Interferences usually are some kinds of "ghost cursors" or
- disappearing cursor image.
-
- "Ghost cursors" may sometimes remain on display at locations where
- cursor no longer exists. These "ghosts" do not affect application
- programs, they only are confusing to the user. With slow computers,
- more interferences of this kind will happen than with fast machines.
-
- The cursor image may also be unstable. Again, this is more likely
- to happen with slow machines.
-
- Sometimes the cursor image may disappear totally. You will get it
- visible again when you hit some key that moves the cursor, for
- example arrow key or space bar.
-
-
-
- 7. FINAL WORD
-
-
- My personal opinion is that Solid Cursor is at its best in text
- processing where one has to move quickly from one location to
- another on the screen. Especially if one uses more than 25 lines on
- the display, a solid non-blinking image is much easier to see than
- the usual small blinking underline.
-
-
-
- 8. BE FREE TO USE
-
-
- The Solid Cursor Program is totally freeware. Be free to use, copy,
- upload and download it just as you wish. However, I do not permit
- selling the program for profit.
