+ The <STRONG>tset</STRONG> command uses these environment variables:
+
+ SHELL
+ tells <STRONG>tset</STRONG> whether to initialize <STRONG>TERM</STRONG> using <STRONG>sh</STRONG> or <STRONG>csh</STRONG>
+ syntax.
+
+ TERM Denotes your terminal type. Each terminal type is
+ distinct, though many are similar.
+
+ TERMCAP
+ may denote the location of a termcap database. If it
+ is not an absolute pathname, e.g., begins with a `/',
+ <STRONG>tset</STRONG> removes the variable from the environment before
+ looking for the terminal description.
