A file is used to store information in the computer. Each file must have a filename and an extension.
A filename is the label you assign to each file for identification. Filenames may contain up to 39 characters. The filename is followed by a period, an extension, and a version in the format filename.extension;version. Filenames should be descriptive of the file contents to make them easier to identify. Use the characters a-z and the numbers 0-9 to name your file. No spaces are allowed.
Extensions are the characters that follow the period in a filename. They are used to help group related files. For instance, letter.txt, papers.txt, and homework.txt would all be text files. Other commonly used extensions include for for a FORTRAN file, dat for a data file, out for an output file, and pas for a Pascal file. Extensions may also be up to 39 characters, consisting of the letters a-z and the numbers 0-9, with no spaces.
Each file also has a version number, separated from the extension by a semicolon, which usually represents how many times the file has been modified. For example, if the project1.dat file has been updated three times, the VAX would display the file as project1.dat;3. In most cases, it is not necessary to specify the version number.
You can edit a file by using the EVE editor. This example opens a file called sample.txt. At the $ prompt, type edit sample.txt. You should see a screen like this:
____________________________________________________________________________ |[End of file] | | | | | | | | | | | | | | | |__________________________________________________________________________| | Buffer: SAMPLE.TXT Write | Insert | Forward | |__________________________________________________________________________|
The following are the four basic cursor movements:

The Internet is a worldwide collection of regional networks communicating using a common protocol called TCP/IP. Electronic mail, remote login, and file transfer capabilities are among the services available. The Internet is available through node Gemini on the Academic and Research Cluster.
TTU's World-Wide Web (WWW) server offers up-to-date campus information as well as easy accessibility to the rest of the Internet, and is accessed through lynx.
To access the WWW, type lynx at the $ prompt. You will see the main TTU WWW Server appear.
The highlighted words and phrases represent hypertext links (hotlinks) to other documents on the WWW. These hotlinks may be local (here on campus) or across the world. To move from link to link, use the up and down arrow keys. To follow a link, use the right arrow key. To move back to a previous link, use the left arrow key. Type h for help, or q to quit.
You may access the online help for lynx by typing h. If you need additional help, contact Academic Computing Support, or refer to the Getting Started With the Internet handout available in CH313.

The file you want to copy must be a public file. Issue the copy command from your account. Note that student accounts reside on the user disk; faculty and staff accounts exist on the research disk.
For example, if you want to copy a file called names.txt from student John Q. Public's (JQU6789) account to your student account (ABC1234) and retain the same filename, type:
copy user:[jqu6789]names.txt *.*
To copy a file called notes.txt from faculty member John Q. Professor's class subdirectory (JPQ1234) to your student account and assign a new filename, type:
copy disk$research:[jqp1234.class]notes.txt newnotes.txt
type filename.ext Display file from your directory
type [directory]filename.ext Display file from another
directory.
type/page filename.ext Display file from your directory
one page at a time
print filename.ext Print file on system printer
print [directory]filename.ext Print a file from another directory
You need READ access from the owner
rprint filename.ext Print a file without displaying it.

A login.com file contains commands that will be executed each time you login to the VAX. A basic login.com is created with each new account. To enhance your login.com file, edit the file with your favorite editor. Most commands should be inserted in the section for commands to be executed in interactive mode. Each command line must begin with a $. Lines that serve as comments begin with $!. Here are some sample commands you may wish to enter:
Changing your DCL prompt
$ set prompt = "Ready! >"
Establishing some shortcuts
$ tp == "type/page"
$ ds == "directory/size"
$ home == "set default sys$login"
$ sq == "show quota"
Defining keys for special functions
$ define/key/nolog pf1 "clear"/terminate
$ define/key/nolog pf2 "mail"/terminate
Any changes you make to your login.com file will automatically take effect the next time you log in.
