 When using an editor, it is essential that the computer be aware

of the type of terminal you are using.   If your terminal type is not

entered properly, your terminal will display many interesting (however

useless and confusing) things.

 Let us assume that your terminal type is vt100.  Before you 

 use an editor, the TERM variable must be made available to all 

 your programs.  To do this you must assign the terminal type to 

 the TERM variable.

 Secondly you need to export the TERM variable.

 Please type setenv TERM vt100 <CR>

 Please type TERM=vt100<CR>

 Then type export TERM<CR>
