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.
