Password protecting 1-2-3 files
If you have a Lotus file that contains sensitive information, it's easy to prevent others from opening the file.
When you're asked to "Enter the name of the file to save," type in the file name, then press the (SPACEBAR) followed by the letter P. Then press (ENTER).
You'll be prompted to enter a password, and from then on you (or anyone else) won't be able to retrieve the worksheet without typing in the password.
