In your biostat terminal window
say vi jvped.dat
then when it opens a blank slate for you, say "a" (append) or "i" (insert)
to put you in insert mode.
Then paste in the file from the web.
Then hit escape to get out of insert mode.
Then try ":wq", and hopefully you have your file!
The ":" takes you down to the foot of the file -- it lets vi know you
are going to give it a command.
The "w" tells vi to write the file, and the "q" is for quit.
Don't type the quote signs (")-- they are just there to make it clearer.
Sorry there is not room for a full vi tutorial here, but you can try the manual pages -- try man vi or man vim.
Of course, use whatever file name you like.
You can rename a file by using the mv command: " mv name1 name2 ".
You can make a new copy of a file by using the cp command: " cp name1 name2 ".
