VAX Auto Login File

     VAX computers also have a file that is read and executed when you 
log on to the system.  The name of the file is login.com.  A com file
on the VAX is like a bat file in DOS and login.com is functionally like
autoexec.bat in DOS.

     I have created a login.com file for you and it is in the ftp
directory if you you would like to use it.  It is
/pub/Internet-course/vax-login.com
FTP to pilot.njin.net and 
cd /pub/Internet-course
then 
get vax-login.com login.com

     This will copy the pilot file vax-login.com to login.com in your
home directory on the VAX.  If you want the file to take effect
immediately enter @login from the $ prompt.  It will automatically
take effect each time you log in.

     A few points so that you can edit and change the file if you like.
The symbol on the left of the assignment statement (==) may be substituted 
for the part on the right.  The right side must be enclosed between double 
quotes.  Entering kermit at the prompt will have the same effect as entering 
run public:kermit.  If a previously defined symbol appears within the double
quotes it must be started with two single quotes and terminated with a 
single quote, forcing the expansion of the symbol.  If you are going to use 
one of your own symbols in another defination it must be previously 
defined.  See the example for pilot.

     Finger is a previousl defined symbol so note its syntax in symbol 
defination for quake.  If you are not sure if something has been defined as 
a symbol enter show sym name where name is the suspected symbol.  It is a 
good idea to check that the symbol that you intend to define has not been 
previously allocated.

     Note the defination of the symbol lib*rary.  Once declared this 
symbol may be entered as lib, libr, libra, libara, or library.  A com file 
is activated from the command line by entering the file name, without the
.com, preceeded with a @.  I find this tedious.  To execute the file 
without the @ prefix simply define a symbol haveing the file name with
the right side enclosure having the @.  The symbol mailit will execute
mailit.com after being defined as
mailit=="@mailit".     

     The following is the contents of the file vax-login.com.
