RDS 6.01 INTERRUPT Problem

We are in the process of moving our applications from 4.XX tools and 5.xx engine on an SCO Unix system to 6.01.UD2 tools and 7.1 On-line on SCO-Unix. We have just noticed that when a user hits the INTERRUPT key the 4GL program core dumps. We have DEFER INTERRUPT and DEFER QUIT in our programs and it worked on the older versions. Has anyone else experienced this? Are there others that are sucessfully using these products on an SCO-Unix machine? Thanks for any feedback! Informix Tech Support is checking into the problem but I could really use an answer sooner. -- Dale Van Voorst voorst@dordt.edu Computer Services postmaster@dordt.edu Dordt College Sioux Center, IA 51250 (712) 722-6299
