At the bottom of the screen there is a space for entering a file name. Up to 20 alphanumeric characters are allowed. It is in this file that the data will be saved automatically as a text file (*.txt) or not at all as determined by the configuration.
The configuration is set the first time the application is launched and at any later date by choosing File - Configure in the main menu.
If the file name entered at the bottom of the screen exists on the hard drive, there will be no prompt for a new name. The computer will rename the file by prepending a number from 0 through 999 inclusive in front of the name previously proposed.
An alert for the name change will be given, make a note of the new name. When the 1000th file with the same root is reached, there is a notice to do some basic file maintenance.
This method saves a lot of time and energy searching for valid names which have not been used and then retyping.
To delete files as they accumulate, use Windows Explorer or FILE-OPEN, then highlight the file and press the delete key.
