-
- APPEND 3.3,X
- /X syntax extended, /PATH added 5.0
-
- ASSIGN 2.0,X (Fundamentally unchanged)
-
- ATTRIB 3.0,X
- H and S attribs added 5.0
-
- BACKUP 2.0,X
- Removed 6.0, replaced with MSBACKUP (crippled Norton Backup)
-
- CHKDSK 1.0,X
- /F, /V added 2.0
-
- CHOICE 6.0,X (Fundamentally unchanged)
-
- The program, for some strange reason, checks for DOS 4 (!) as the
- minimum OS required. However, I have cajoled it into running on
- DOSPLUS, which claims DOS 2.11 compatibility (and isn't too good
- at that either).
-
- COMP 1.0,X
- Rewritten 5.0, switches were not supported before then
- Removed 6.0
-
- DEBUG 1.0,X
- Mini-assembler added 2.0
-
- DEFRAG 6.0,X (Fundamentally unchanged)
-
- DELTREE 6.0,X (Fundamentally unchanged)
-
- DISKCOMP 1.0,X
- /1 added 1.1, /8 added 2.0
-
- DISKCOPY 1.0,X
- /1 added 1.1, /8 added 2.0
-
- DISPLAY.SYS 3.3,D (Fundamentally unchanged)
-
- DRIVER.SYS 3.2,D (Fundamentally unchanged)
-
- FASTHELP 5.0,X (was called HELP in 5; current name from 6.0)
-
- FASTOPEN 3.3,X (Fundamentally unchanged)
-
- FC 2.11,X (Fundamentally unchanged)
-
- "Special Edition Using MS-DOS 6.22 Second Edition" says this is new
- to 3.3 - sorry, but that's false. Before IBM DOS 5.0, it was only
- included with Microsoft's version of DOS; however, I have found FC
- in Tandy, Osborne and Victor OEM versions of DOS 2.11. It was
- certainly not included in DOS 1.25, although a similar program
- called FILCOM is present in the Corona OEM and bears a Microsoft
- copyright. I also spotted FC in Seiko-Epson MS-DOS 3.2.
-
- FDISK 2.0,X
-
- This wasn't included in a lot of early OEM versions of DOS (prior
- to 3.2, anyway). Some OEMs rolled their own FDISK replacements,
- such as Zenith. IBM uses a different codebase from MS, although
- their programs are similar in interface.
-
- FIND 2.0,X (Fundamentally unchanged until PC DOS 7)
-
- FORMAT 1.0,X
- /V modified 4.0
- /Q, /U added 5.0
- /N, /T added 3.3
- /8 added 2.0
- /4 added 3.1
- /1 added 1.1
- Undocumented switch /H in DOS 3.30 only?
- Undocumented switches /AUTOTEST, /BACKUP, /SELECT in 4.0
- and later; some combinations of these switches do not
- work in 4.0-6.22 or in 95> but do work in PC DOS 7.
-
- Prior to version 2, the syntax for FORMAT varied dramatically from
- machine to machine. Zenith MS-DOS 1.25 had a whole slew of options
- that were not in standard FORMAT; one /C option looked to be similar
- to the /Q option provided in DOS 5!
-
- GRAFTABL 3.0,X
- Removed 6.0
-
- GRAPHICS 2.0,X
- Some formats and switches added around DOS 3.2?
- Extended with additional formats and external config file
- in DOS 4.0
-
- HELP 6.0,X
-
- JOIN 3.2,X
-
- KBDBUF.SYS DOS 6 Supplemental,D
-
- KEYB 3.3,X
-
- LABEL 3.0,X
-
- MEM 4.0,X
-
- Rewritten for DOS 5. DOS 4 accepts the /DEBUG, /PROGRAM switches;
- DOS 5 takes these plus /CLASSIFY; DOS 6 removes /PROGRAM and adds
- /PAGE, /FREE and /MODULE module. All switches can be abbreviated
- to one letter.
-
- MODE 1.1,X
-
- Over time, MODE has evolved to support new DOS features. This are
- frequent and I am not going to mention the differences from version
- to version. There are also so many different functions, and I
- expect these are well-known already.
-
- MORE 2.0,X
-
- Windows 95 takes an optional filename; AFAIK no other versions of
- DOS support that syntax (FD excluded). Also, in DR DOS, MORE is
- an internal command (!).
-
- MOVE 6.0,X
-
- MSCDEX 6.0,X
-
- MSD 6.0,X
-
- MSHERC 5.0,X
- Only in 5.0 and various versions of MS compiled BASIC
-
- This program provides a BIOS extension (mode 8 for int10?) which
- can be used to easily access the graphics mode on the Hercules
- video adapter. It has no use on other systems. There is one
- switch, /HALF, which prevents the CGA memory area from being used
- as Hercules memory (?). It is mainly for programs written in
- variants of QuickBasic 4 and later (including VBDOS 1 and QBasic).
-
- NLSFUNC 3.3,X
-
- PRINT 2.0,X
-
- RECOVER 2.0,X
-
- This is so dangerous that it's not even on DOS 6's Supplemental
- Disk! Actually, SCANDISK has assumed the functionality of RECOVER
- and does a much better job.
-
- REPLACE 3.2,X
-
- RESTORE 2.0,X
-
- SCANDISK 6.2,X
-
- SORT 2.0,X
-
- SUBST 3.1,X
-
- SYS 1.0,X
-
- Before DOS 5, COMMAND.COM was not copied by SYS. There are
- additional restrictions prior to DOS 4.
-
- TREE 2.0,X
- Rewritten 4.0
-
- UNDELETE 5.0,X
- Crippled except in PC DOS 7
-
- UNFORMAT 5.0,X
-
- XCOPY 3.2,X
