Changing shell variables

The C and TC shells have a number of local shell variables which are not exported to the environment. To make sure that these variables are picked up whenever a new shell is invoked, always define shell variables in your .cshrc (.tcshrc) file.

By convention, names of shell variables are always given in lower case letters. UNIX is case sensitive, so the environment variable PATH is not the same as the shell variable "path".
