Environment Variables

Environment variables is the mechanism used in DNC-Max to store system information. Environment variables are specified by '$' followed by the variable name. E.g. the name of directory where port log files are saved, is stored in the environment variable $LOG.

Environment variables can be defined as a composition of other environment variables. E.g. the default log directory $LOG, is normally defined as $MACHINE\LOG, where $MACHINE is defined as $ROOT\$PORTNAME.

There are four different groups of environment variables: Global, Directory, Report and NC variables.
