Assign values to the environment variables, and make their path names meaningful.
For example, define CATCollectionStandard as C:CATIAV5R21standard (for
Windows) or /CATIA/V5R21/standard (for AIX). For CATReferenceSettingPath, define it as C:CATIAV5R21catlock (Windows) or /CATIA/V5R21/catlock (AIX).
After making the modifications to the environment, save the changes by right-mouse- clicking in the lower pane of the Environment Editor Window to access its contextual menu, then select Save.
