The Startup Script TkIrc.pl

The file /online_dir/TkIrc.pl is executed during program start once per session. If it has been changed, Online has to be re-started before the changes come into effect. TkIRc.pl can be changed from within online -tki. There is an item 'emacs TkIrc.pl' in the Misc menu button.

The startup files are executed in this order:

1. /online_dir/exp_ini.exp
2. ./spectra_ini.gra
3. /online_dir/TkIrc.pl

The purpose of TkIrc.pl is:

• Select applications, see section 6.9 for details.

• Introduce beam line specific code, see section 14.

• Define functions that can be use from virtual motors, virtual counters, scripts, etc.

• Load the Tango configuration file /online_dir/online.xml. This is done by the statement: Spectra::load_configuration();. More details about online.xml can be found in the Online manual.
