Where are the constants loaded ?

Would like to know which file the system constants are loaded, in particular the DB_TABLE constants.
Thanks
Steve

Answering my own question, I believe:  Found the file / includes/config.inc.php  on my website.  It was not present on my local development computer.  I presume it was a file generated during the installation...?

Yes the file is generated by the installer. Otherwise you would damage your installation while upgrading, since you overwrite files while uploading the upgrade.
