+-------------------------------------------------------------------+ | IN BRIEF . . . | | | | PC DOC V7 is the best, industry-standard DOS for new and upgrade | | DOS/Windows users. Features include: | | | | o Easy install and upgrades from any DOS Version 3.3, or later | | | | o Increased memory for applications | | | | o Integrated Stacker** 4.0 compression breaks the 2:1 barrier | | for disk optimization | | | | o IBM AntiVirus protection for over 2,100 viruses | | | | To subscribe for updates, call IBM AntiVirus Services at | | 800-742-2493. | | | | o Online command reference and Help information | | | | o Enhancements to PC DOS best-of-breed, full-function utilities | | including: | | | | - Central Point's Backup Utility | | - Phoenix Technology Laboratory's PCMCIA support | | - RAMBoost Memory Optimizer | | | | o REXX programming language support | | | | o PC DOS File Update automatically synchronizes files between | | two systems | | | | o Support for docking stations | | | | o E Editor with math and mouse support and enhanced user | | interface | | | | o Scheduler lets you schedule any DOS program or batch file for | | unattended use | | | | o Undelete recovers previously deleted files | | | +-------------------------------------------------------------------+IBM PC DOS Version 7 further enhances IBM's line of award-winning operating systems with improved usability, memory optimization, full-function utilities, and new hardware support.
PC DOS Version 7 requires less conventional memory than DOS 6.X versions for comparable function. By employing a variety of memory reduction techniques, more conventional memory is available for user applications and industry-standard compatibility is maintained.
IBM AntiVirus protects your data with superior integrated virus detection software. This software provides protection for over 2,100 viruses with one of the smallest memory footprints in the industry.
PC DOS Version 7 incorporates the latest technology in our full-function DOS and Windows+ utilities:
PC DOS REXX, a high-level programming language, is powerful, easy-to-use and portable across many operating systems. PC DOS REXX includes standard and advanced functions, BAT file commands, and arithmetic operations.
Maximum disk compression with Stacker 4.0. Stac Electronics Stacker** 4.0 advanced disk compression technology gives you the highest compression ratio and most free disk space possible. You can upgrade from prior disk compression technologies such as MS-DOS DoubleSpace/DriveSpace, PC DOS SuperStor/DS, and earlier versions of Stacker. This support is designed to use little conventional memory.
Help when you need it. A comprehensive online help system gives you hypertext links, search capability, and easy access to index, contents, and print functions.
PC DOS File Update keeps your work files current. This new utility automatically updates files between two personal computers so you can easily synchronize files between your mobile and desktop computer or vice versa.
New docking station support for mobile users helps you define a specific command or batch file to execute automatically each time you dock or undock.
Easy editing of one or more files is at your fingertips with the improved E Editor. With complete mouse and pull-down menu support, editing is easier than ever. Other new features include browse mode, enhanced delete recovery, enhanced math and search support, and REXX autosyntax support.

When less memory is used by DOS, more memory is available for the user's applications. This means the user can use larger or more applications than may otherwise have been possible. It also means that applications will have more memory available to use as buffers, which, in some cases, allows the application to run faster.
ANTIVIRUS PROTECTION
IBM AntiVirus provides protection from major categories of viruses including:
This support substantially reduces the risk of system failures that might be caused through the use of electronic bulletin boards and data sharing. Viruses can be detected and neutralized without damaging the user's data files or applications.
As an added benefit, this superb protection requires very little conventional memory.
FULL-FUNCTION DOS AND WINDOWS UTILITIES
PC DOS Version 7 includes an update to many of its best-known utilities (besides IBM AntiVirus) and the addition of new utilities.
The following utilities are enhanced:
The new utilities in PC DOS Version 7 are:
Like its predecessor, PC DOS Version 7 contains a wide assortment of full-function utilities to handle many common tasks. The inclusion of these utilities may eliminate or significantly reduce the need for users to supplement their system software with additional tools. These utilities are included in PC DOS Version 7:
Note: To use Windows-based applications, games, and utilities, you must have Windows 3.1, or later, installed on the system.
PC DOS REXX
PC DOS REXX support provides a simple yet powerful tool for writing programs to perform unique but commonly performed tasks. This support eliminates the need for users to separately purchase a programming language to build simple programs.
Specified Operating Environment
Hardware Requirements: PC DOS Version 7 operates on Intel**-based or Intel-compatible personal computers (808X, 286, 386, 486, and Pentium processors).
A minimum of 512KB of processor system memory is required. A new system (one without a previous version of DOS installed) must also have a high-density, 3.5-inch or 5.25-inch A: diskette drive. The PC DOS Version 7 upgrade requires a system with a prior version of DOS (any DOS Version 3.3, or later, including MS-DOS) installed on the hard disk. Installation on upgrade systems can occur from any high-density diskette drive, CD-ROM, or from the network to the hard disk. Installation from a CD-ROM requires a previously installed CD-ROM driver. The minimum disk space required for PC DOS Version 7 is 6MB, if all defaults are taken on installation. The maximum disk space required for PC DOS Version 7 is 18.5MB if all features for both DOS and Windows are installed.
Software Requirements: PC DOS Version 7 maintains upward compatibility with prior versions of DOS. Functions supported on previous levels will continue to be supported, unless that specific function is no longer supported by IBM.
Functions no longer supported in PC DOS Version 7 are:
These commands from prior versions of DOS will not be deleted by the installation of an upgrade to PC DOS Version 7 and are expected to run compatibly with PC DOS Version 7 when used with the SETVER command. If these commands are needed on systems with PC DOS Version 7 and the customer has a license of PC DOS Version 6.3, the customer is authorized to copy the files to support these commands to all licensed PC DOS Version 7 systems where these files are required. Refer to the license information included with the product for details on the files that may be copied.
Limitations: Applications supported on previous levels of DOS should run compatibly with PC DOS Version 7. However, with each release of DOS, adding new features introduces some incompatibilities. Below is a list of changes that may cause compatibility problems.
To run Windows-based applications, games, and utilities, you need to have Windows 3.1, or later, installed on your system.
Security, Auditability, and Control
IBM AntiVirus updates are included in PC DOS Version 7. This support helps users automatically detect and neutralize known stealth, polymorphic, generic, and even unknown viruses without damaging the customer's files or applications. Today, this support detects over 2,100 known viruses. Though PC DOS Version 7 offers superior integrated anti-virus support, new viruses are discovered regularly. IBM offers an update program separately for users to stay as current as possible with this protection.
There are no new auditability or control features in PC DOS Version 7.
User management is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communication facilities.
