The download consists of a single executable called WZCLINE20.EXE (for WinZip version 9 the required file is called WZCLINE9.EXE). If you are running an older version of WinZip, the corresponding download will have to be sourced elsewhere. In addition, it requires the Windows 98, ME, 2000 or XP operating system. GETTING STARTED The WinZip Command Line Add-On is available for download at Only the most recent version is available, which at the time of writing is the version compatible with WinZip 10.0 Pro. The macros and examples given in this paper are available for download from contained in a zip file called WZ_Test.zip. They should help to make it easier to use this software from within SAS. Two SAS macros are then presented, %WZZIP and %WZUNZIP. This is followed by a number of examples which should demonstrate how the two commands can be used directly from the MS DOS command prompt or from within SAS. These can be used to zip (compress) and unzip (de-compress) files respectively. Once set up, the two commands, WZZIP and WZUNZIP become available as MS DOS commands. This paper firstly gives an outline as to how to get started with the WinZip Command Line Add-On.

What can be done via the WinZip graphical user interface can, when necessary, be automated. The advantage of having these commands is that accessing the functionality of the WinZip utility becomes enormously flexible. The WinZip Command Line Add-On is available for free and provides all the functionality of the WinZip utility through two additional MS DOS commands, namely, WZZIP and WZUNZIP. Whilst the interface is easy to use, managing files with it can be tedious and prone to error. This utility offers a method of archiving files in a compressed and/or encrypted form. INTRODUCTION For those not familiar with WinZip software, it provides a compression utility for use in a Windows environment.

It is very simple to use and can be readily employed in various ways, including via SAS, to automate what would otherwise be achieved through WinZip's graphical user interface. The WinZip Command Line Add-On provides the MS DOS command prompt equivalent to the WinZip utility. 1 Paper CC01 A Quick Guide to the WinZip Command Line Add-On David Brennan, Independent Contractor, Dungarvan, Ireland ABSTRACT If you are running SAS under Microsoft Windows, it could be worthwhile exploring the use of WinZip along with the WinZip Command Line Add-On.
