Saving And Loading Files
There are two ways to save in Logo. One is the traditional method shown below of file |save. The other is in keeping with text based programming and is important for students to learn in their programming journey. Choose the method that best aligns with your age group and goals of your classroom.
For new and younger users you will probably want to start with the traditional file | save as described below. Please review the different files types for saving. However when your students are ready, have your students use the save command. By doing this you are introducing your students to a realistic programming environment. Following is an example of how to use the SAVE command.
Please note that the Web version cannot save to any disk location because of security restrictions. The Web version always saves to the browser’s Downloads folder.
Save with menu toolbar
To save, select File from the toolbar then select save, a dialog appears with six choices.
Workspace as Logo File (.lgo)
Saves all procedures as well as the global names and property lists, including the current preferences as the PREFS property list as a text file with te extension ”.lgo“. You can edit the file with any editor, or load it back into the Logo workspace, or into the Logo editor.
Saves everything in the listener panel, graphics panel, editor panel, and any procedures, names, and property lists created. This is the best choice for students who are working on a project or new to Logo; when you load a .logoenv file, Logo restores the complete enviroment to the state that was saved.
Editor Contents (.lgo)
Saves what is currently being written in the editor panel. This is a good choice if a student is working on a procedure in an editor panel and is not finished, or if the student loaded a ”.lgo“ file into the editor.
Files Panel (.zip)
Saves all files that the
~FILES panel displays into a zip file.
Saves the graphic panel as a graphic image in a .png format.
