* In the current configuration PACS5 is the operational database and "pacs_fm_ilt_3" is the operational database
 * To achieve versioning control, any change to '''CUS''' (amended or new script) will generate a new CUS model.
 * Scripts may be amended/created using the built-in editor of the CUSGUI, or standard editting of the ASCII copy of the script, to be found in the directory /home/oper/toREG/Name_of_Script.cus
 * If the script was modified within the CUSGUI, you must ''Commit'' your changes. If you have amended/created a file in toREG/, you must issue ''cus -f -import Name_of_Script.cus''
 * A dedicated procedure, invoked as '''''ccm -updatecus''''', creates the new model, updates the local CVS, and conditions '''testcontrol''' to work with the new model.
 * Only the test conductor should perform the ''updatecus'' procedure (the procedure stops testcontrol, causing any running TOPE task to abort in error)
