Starting SPECTRA

An interactive SPECTRA session is started by:

> spectra [-ddisplay] [-online] [-nographic] [-s [-pport_no]] [-v]

The meaning of the qualifier:

• -s: The name of the X server, e.g.: -sxtr007:0. By default SPECTRA uses the DISPLAY variable to find the X server.
• -nographic: Graphics output is suppressed.
• -online: SPECTRA runs in the ONLINE mode.
• -s: Starts the server mode. Any output is suppressed, except:

  'done'	For successfully completed commands.
  'error'	For commands that returned an error.
  $value$	In response to a statement like: '$*$=energy()'.

  See the ONLINE manual for the description of the verb server.
• -p: Selects the TCP port number for the server I/O, e.g.: spectra -online -s -p7777
• -v: All messages that are exchanged in the server mode are displayed.

SPECTRA uses the following environment variables:

DISPLAY	The X server. There is no need to set it, if SPECTRA runs on local host or via a secure connection (ssh).
EDITOR	Specifies the editor which is called from edit commands or certain full screen menu actions. By default SPECTRA uses $vi$.
XPS_TERM	Specifies the terminals type. By default SPECTRA generates X output.
ONLINE_DIR	The on-line directory, by default SPECTRA uses /online_dir. This variable has to be set, if SPECTRA runs in the on-line simulation mode.
EXP_DEVICE_LIST	The device list, default on_line.dev on the on-line directory.
EXP_INI_LIST	The on-line startup file, default exp_ini.exp on the on-line directory.
EXP_ON_LINE_EXIT	The on-line exit file, default on_line_exit.gra on the on-line directory.
