Paths and Directories

These variables set the search paths (see 1.2.4) and document directory used in Xic. These have counterpart environment variables (see 1.2.3). The search paths can also be set from the technology file.

If not set by any means, internal defaults are used for the search paths and document directory. Under Windows, the default is set to point to the actual installation location subdirectories when necessary. Under Unix/Linux, the XT_PREFIX environment variable should be set to the installation location prefix that effectively replaces ``/usr/local''.

Below, PREFIX is obtained from the Windows Registry database under Windows, which is defined when the program is installed. Under Unix/Linux, PREFIX is obtained from the XT_PREFIX environment variable. In both cases, the default value for PREFIX, if another definition is not found, is ``/usr/local''.

Path
Value: path string, can't be unset.
This variable contains the symbol search path. It is always defined, and can not be unset. This path is used to find symbol files and libraries containing symbol files.

If not set by any means, a default symbol path is used.
Default: ``( . )''

LibPath
Value: path string, can't be unset.
This variable contains the startup library search path. It is always defined, and can not be unset. The library path is used to find the technology file, device and model libraries, and other initialization files.

Unlike other search paths, the current directory is always searched first, whether or not this is indicated in the search path string. If not set by any means, a default library path is used.
Default: ``( . PREFIX/lib/xictools/xic/startup )''

HelpPath
Value: path string, can't be unset.
This variable contains the help search path. It is always defined, and can not be unset. This path is used to find files that contain information for the help system.

If not set by any means, a default help path is used.
Default: ``( PREFIX/lib/xictools/xic/help )''

ScriptPath
Value: path string, can't be unset.
This variable contains the script search path. It is always defined, and can not be unset. This path is used to find script and menu files that will appear in the User Menu.

If not set by any means, a default script path is used.
Default: ``( PREFIX/lib/xictools/xic/scripts )''

DocsDir
Value: path to directory.
The given directory is searched for the release notes, for the Release Notes command in the Help Menu.

If not set by any means, a default document directory is used.
Default: ``PREFIX/lib/xictools/xic/docs''

TeePrompt
Value: path to file.
When set, the prompt line messages are copied to the given file. If a file name is not given, or when the variable is unset, redirection stops. The value string can be ``stderr'' or ``stdout'' to redirect output to the terminal window instead of a file.
