When using private data sessions a number of environment setting are overridden by the data session and set to the default settings. SET CENTURY is one of these. You probably need to SET CENTURY again within your form. I issue all the set commands to set my environment in the Load event of my base form class. See the SET DATASESSION help topic for a list of settings overridden by private data sessions
