- What is new in version 4.20
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- *DOS-5 aware*
- Modified the upper-memory self-loading service of switch H, and the global
- DOS enviroment service of switch E to be compatible with DOS 5. Prior VIz
- versions executed under DOS 5.0 are: (1) unable to self-load in the upper
- memory when UMBs allocation is controlled by DOS (DOS=UMB), instead of the
- XMS manager, and (2) unable to create the 'VIZ' variable in the global DOS
- environment when DOS 5.0 has been installed in the High Memory Area rather
- than low conventional memory. Fixed error in the implementation of the 35
- line font in 386+ version.
-
-
-
- What is new in version 4.17
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Fixed error in the Status/Usage/Help display panel. Added further changes
- for 386+ code optimization. Fixed error in 14-line font in 486+ version.
-
-
- What is new in version 4.16
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Added further routines for support of HERCULES (HGC and HGC+) cards. Fixed
- harmless error in the ANSI module that resulted in error message if switch
- /A+ was issued before switch /A- after the installation of the module. The
- updating of resident parameters was improved. Added more video support for
- 14-line (VGA) or 12-line (EGA) screen displays. Fixed mouse bug introduced
- in version 4.12.
-
-
- What is new in version 4.15
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Corrected assembler (phase?) error which resulted in a wrong memory segment
- override, an error that had unpredictable effects on the DOS shell when the
- accelerator module alone was resident. ** USERS WITH VERSION 4.12 OR HIGHER
- NEED TO UPGRADE EVEN IF PROBLEMS WERE NOT EXPERIENCED **
-
- Acceleration module optimization for the 486 version. Corrected apparently
- harmless error in the nonresident component (cursor position update). Fixed
- bug affecting the proper updating of screens with more than 25 lines. Added
- 12-line, 28-line and 35-line screen fonts via switch F, which now accepts a
- 2-digit decimal number between 12 and 50 (/Fn) and can be used to enforce a
- given font size. Corrected (486) CPU flags error when testing for processor
- type with 286+ machines, which affected behavior when an invalid switch was
- selected. Added switch S2 to enable/disable the <Ctrl><NumLock> combination
- (the <Pause> key in PS/2s and COMPAQs) that can crash a LAN if pressed on a
- LAN server. Switch S1 now enables/disables the <PrtSc> key, which can also
- crash a system if the printer is not on line when this key is pressed. The
- default condition of switch N is now /N- (nonfatal messages are displayed);
- this change can be neutralized by selecting /N+ on installation. Corrected
- error in the status display for switch S1 (old switch S) in the status/Help
- panel. Byte or word OUT commands can now be tested by entering 'VIZ /?H' to
- see if the cursor appears at the screen center; this service supersedes the
- TESTOUT.EXE utility.
-
-
- What is new in version 4.14
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- ANSI module optimization for the 486 version. Corrected pointer error that
- trashed part of the Status display in video modes other than 80 columns and
- corrected display of the current video mode. The Status/Help display panel
- attributes in MCGA/VGA monochrome mode were adjusted to improve readability
- of the text.
-
-
- What is new in version 4.13
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The self-loading into high memory has been improved for a faster processing
- when dealing with the XMS manager. The user can now request a minimum high-
- memory bound above which the program should load itself (if an upper-memory
- block is available above the limit). This helps to avoid high-memory areas
- that have slow a memory access time. (The utility TIMEM.EXE can be used to
- measure access times.) Real mode 486 version introduced.
-
-
- What is new in version 4.12
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The Usage/Status/Help panel was reorganized for clarity; mouse support was
- added to facilitate the various displays. On-line Help text was added and
- some non-resident video display routines were improved.
-
-
- What is new in version 4.10
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Resident was changed to permit use of self-modifying code to increase video
- acceleration performance, including the ANSI filter. Both resident and non-
- resident routines have also been improved for faster operation in 086, 286,
- and 386+ processors.
-
-
- What is new in version 4.03
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The DOS environment variable 'VIZ' can now be directly updated or created in
- the (master) DOS environment by means of switch /E. Unlike the SET command,
- which modifies the default environment block (whether it is the global [i.e.
- that used by the initial copy of COMMAND.COM] or a local one [i.e. that used
- by a secondary copy]), switch /E always modifies the global DOS environment.
- This allows to modify the environment variable even when 'shelling out' from
- any application, in which case the SET command would not be useful to modify
- the environment block. Resident and non-resident 386-specific code has been
- tightened in the 386 release. A minor bug in single-digit octal input (/Bn)
- has been fixed. ANSI performance has been improved a little more.
-
-
- What is new in version 4.02
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Direct high-memory loading introduced. Switch /L allows the resident code to
- be installed directly in high memory (i.e. at conventional memory between 640
- kb and 1,024 kb [1 Mb]). This avoids not only the initial load sizing of the
- program by some (386) memory managers, but also the need to have available up
- to 64 kb of free high memory to install a resident of less than 1 kb. An EXE
- format has been reintroduced as it provides better file compression.
-
-
- What is new in version 4.01
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Further tightening of resident code to improve acceleration performance in 32
- bit bus 386+ machines.
-
-
- What is new in version 4.00
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Real mode 386 version introduced. See VIZ.DAT for comparisons with 16-bit and
- 32-bit bus machines. Fixed problem in cursor positioning when first installed
- without initial scrolling of the screen.
