The value of this constant is returned by the file-exists function to indicate that the target file is readable.
Controls whether or not a buffer can be modified. When read-only-buffer is set to true, all attempts to modify the buffer will be ignored and will result in an error.
The value of this constant is returned by the file-exists function to indicate that the target file can be read and written.
Controls the removal of the help window. When non-zero, help windows that have been automatically popped up onto the screen are removed. Otherwise, the help window will stay on the screen after the help function has completed.
Controls the case of replacement text. If non-zero, Emacs will alter the case of strings substituted with replace-string or query-replace-string to match the case of the original string.
Controls the Replace minor mode. If non-zero, characters inserted into the buffer replace existing characters, rather then inserting (the default). This can be useful when editing diagrams.
This read-only variable is a count of the number of times that the current environment has been saved and restored. If Emacs has not been restored from a saved environment file, restored-environment is zero.
Contains the name of an Emacs function which will be called when Emacs returns from DCL after a pause-emacs or return-to-monitor command. You can assign the name of any existing function to the variable.
Controls the right margin setting for automatic text justification. If a character is inserted at the end of a line to the right of right-margin, Emacs will automatically insert at the beginning of the preceding word a newline, tabs and spaces to indent to the left margin, and the prefix string. For example, with right-margin set to 72, you can type in a document without worrying about when to hit the Return key; Emacs will automatically do this for you at exactly the right place.
