- We don't know if the following text fie is accurate or not since it came from
- "scuttlebutt", we picked up here and there. But we present it here as a sort
- of `wish list' for us Dossers.

- Well, DOS 5.00 will probably be out by the end of 1990, and you are probably
- anxious to know what is new. Most people either don't know what is new, or
- "can't tell you". We'll tell you all we know (and some stuff on our "wish
- list").

-
- Changes/Additions:
-
- 1. DOS can now load itself into the first 64K of Extended memory if
- you have it. You must have the line, "DOS=HIGH" in your config.sys
- and you must have at least 64K of extended memory available. This
- will only work on AT machines since 8088/8086 processors can only
- address up to 1 Megabyte of memory, and Extended Memory begins at
- 1 Meg. Loading DOS high will free up quite a bit of valuable
- conventional memory.
-
- 2. The QuickBasic interpreter is included along with GWBasic.
-
-
-
-
-
-
-
-
-
- 3. The Shell program (DOSSHELL) has been completely changed. It now
- resembles the "File Manager" Program that comes with Windows or
- OS/2. DOSSHELL can be run in either graphics or text mode, in
- color or black and white. The F1 key brings up online help.
-
- 4. If the environment variable "TEMP" is set, DOS will use the
- directory set in "TEMP" to write temporary files for piping
- operations. If there is no "TEMP" directory set, the current
- directory is used.
-
- 5. If the environment variable "DIRCMD" is set, DOS uses it for
- all "DIR" commands. For example, if "DIRCMD=/W", when you type
- "DIR", DOS would act like you typed "DIR/W" (Wide display).
-
- 6. A short help screen is available for all DOS commands by adding
- a "/?" after the command, for example, "DIR /?" would give you
- a help screen for the DIR command.
-
-
-
-
-
-
-
-
-
-
- 7. There is a utility called "DOSKEY" that is basically a command
- line editor that lets you backup through your previous DOS
- commands. Here is the help screen for DOSKEY:
-
-
-
- DOSKEY [/reinstall] [/bufsize=] [/dmacs] [/dhist] [macro=text]
- /reinstall Installs a new copy of doskey.
- /bufsize= Specifies the size of the command buffer.
- /dmacs Displays all macros and lets you redirect them to a file.
- /dhist Displays all command lines stored in memory.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- 8. A program called UNFORMAT is included. It restores a hard drive
- to its condition prior to the last FORMAT command.
-
-
-
-
-
-
-
-
-
-
- 9. The DIR command now reports how many bytes the files listed
- total up to. Here is an example DIR command:
-
- E:\>dir
-
- Volume in drive E is whatever
- Directory of E:\
-
- WIERDOS <DIR> 06-28-90 12:42a
- DUDE ZIP 724409 07-26-90 10:14p
- TMP <DIR> 07-28-90 6:32p
- IHATE-U <DIR> 06-28-90 12:42a
- MASM EXE 103175 07-31-87 12:00a
- STSCFG CFG 2339 04-30-90 1:49a
- SD INI 2497 07-13-90 2:52a
- FRECOVER DAT 50688 07-14-90 1:25a
- 8 File(s) 3883108 bytes
- 21868544 bytes free

- There is also a neat little program included with the beta
- version of DOS 5.0 called "Microsoft Infer". We don't know if Infer
- will be included with the release version of DOS. Infer tells lots
- of useful information about your system, like: Operating System
- Version, Machine type, Environment, Processor type, Memory info,
- Video Adapter info, Serial/Parallel port info, disk drive info,
- and much more. Infer includes a ROM BIOS browser, memory browser,
- and several other useful functions. How about <THAT> for a wish list?
