Saving Files
After making changes to an file, you see an asteris k (*) next to the filename
in the title bar of the Editor/Debugger. This indicates there are unsaved
changes to the file.
To save the changes, use one of the Save commands in the File menu:
• Save —Savesthefileusingitsexistingname. Ifthefileisnewlycreated,
the Save file as dialog box opens, where you assign a name to the file
beforesavingit.AnotherwaytosaveisbyusingtheSavebutton
on the
toolbar. If the file has not been changed, Save is grayed out, but you can
instead use Save As from the File menu to save to a different filename.
• Save As —TheSave file as dialog box opens, where you assign a name to
the file and save it. By default, i f you do not type an e xtension, MATLAB
automatically assigns the
.m extension t o the filename. If you do n ot want
an extension, type a
. (period) after the filename.
• Save All — Saves all named files to their existing filenames. For all newly
created files, the Save file as dialog box opens, where you assign a name to
each untitled file and save it.

displays a dialog box asking if you want to exit debug mode and then save

there are unsaved changes — see “Running Sections in M-Files That Have
