DOS Windows, Text Editors, blah blah.

Useful DOS Stuff

• cd _directory_ - Change to a particular directory.
• dir - Displays the contents of the current directory.
• dir /od - Display contents sorted by date (most recent at bottom.)
• dir /ad - Display any directories within the current directory.
• cls - Clear the screen.
• up arrow, down arrow - Scroll through the list of commands you've entered.
• ctrl-C - (hold down Ctrl key and press "C" at the same time) Stop a program from running.   For example, if you are in an infinite loop.
  

Editing with Notepad

• Notepad is annoying to use; we are looking for a better replacement.
• Until then:
  • Enter notepad at a DOS prompt (for a new file), or notepad _file-name_ to edit a file that already exists.
    • For example: notepad program1.pl
  • Edit your file.
  • If the file already has a name (that is, it has already been saved once), you can just do ctrl-S to save it as the same name.
  • If you are saving for the first time:
    • Pull down the menu file and then save.
    • Navigate to the directory you want to save to.
    • Under Save as type select all files.
    • Enter the filename with a .pl at the end.
    • Save it.
