We are planning to install 6.5 on 4 HP3000's but we only have a COBOL Compiler on our development box. Since we always do new installs on our test box first, we will end up with a 6.5 compiler on the development box. I understand from HP that 6.5 compiled programs will not run on 5.5. Has anyone run into this dilemma and if so, how did you resolve it? Any help would be greatly appreciated. Jerry Hewett HP3000 Systems Manager Hanover Direct, Inc.
