Each argument is expanded if it is aliased, and searched for along the user's path. Both aliases and path are taken from the user's .cshrc file. Restrictions Must be executed by a csh, since only csh's know about aliases. Diagnostics A diagnostic is given for names which are aliased to more than a single word, or if an executable file with the argument name was not found in the path.
