If TESTENV.BAT indicates you don't have adequate environment space to run the examples, you'll need to modify your DOS window so it has at least 1024 bytes of environment space. To do this in Windows 95 or 98, do the following: (1) create a MS-DOS prompt icon by using the program "command" or by using or copying an existing one. (2) Right-click on the icon and select "properties". (3) Select the "memory" tab. (4) Select "1024" or higher in the pull-down menu in the "initial environment" field. (5) select "ok". However, as long as you're doing this, you might as well also go to the "program" tab and give the installation root directory as the working directory, and "NEWENV.BAT as the "batch file." This way These procedures do not work with Windows NT, but the environment probably should be adequate in the first place. The Windows NT "help" gives no information in this regard. For a raw DOS or Windows 3.1 system, put the following in the CONFIG.SYS file on the boot disk, and reboot: SHELL=C:\DOS\COMMAND.COM /P /E:1024. This is not necessary for Windows 95 or higher.
