System configuration options discussed in this section are specific to MS-DOS versions
5.0 and 6.x and have been tested under MS-DOS, Windows 3.xx, Windows NT,
Windows 95, OS/2 and Novell Netware.
The Setup program may require file sharing services (SHARE.EXE in your computer’s
AUTOEXEC.BAT or CONFIG.SYS file in Windows v3.1 or VSHARE.386 in
SYSTEM.INI in Windows for Workgroups) in some cases when the copy protection is
located on a network drive.
The A.I. Series software recognizes an environment variable called PLCLL. This
variable is used by the executable files to locate configuration and other system files.
All A.I. Series programs recognize and use the PLCLL variable. In a multitasking or
networked environment, the variable must be used to specify a unique drive and
directory for each user or session. Each user or session must have read/write access to
the drive and directory specified by PLCLL. If the environment variable is not
specified, the current directory is used.
