|  3.1.1 How to enter and exit 
SINGULAR can either be run in an ASCII-terminal or within Emacs.
 
To start SINGULAR in its ASCII-terminal user interface,  enter
Singularat the system prompt. The SINGULAR banner appears which,
among other data, reports the version and the compilation date. 
To start SINGULAR in its Emacs user interface, either enter
ESingularat the system prompt, or typeM-x singularwithin a running Emacs (provided you have loaded the filesingular.elin your running Emacs, see  Running SINGULAR under Emacs for details). 
Generally, we recommend to use SINGULAR in its Emacs interface,
since this offers many more features and is more convenient to
use than the ASCII-terminal interface (see  Emacs user interface).
 
To exit SINGULAR type quit;,exit;or$(or,
when running within Emacs preferably typeC-c $). 
SINGULAR and ESingularmay also be started with command line
options and with
filenames as arguments. More generally, the startup syntax is |  | Singular  [options] [file1 [file2 ...]]
ESingular  [options] [file1 [file2 ...]]
