Someone else, too. I've thought about doing that here in our system. If a common function changes, it's just a matter of changing the function itself and moving the whole library into production. Of course, it would be hard to test any 'number of parameters' changes. I did some testing about a year and a half ago. I played around with it, and it seemed to work pretty well. Just never had the chance to follow through on it. I'll attempt to find my notes if you're interested. 4gl 6.02 Informix 7.13/7.23 HPUX 10.01 John Carlson Informix DBA WH Smith, Inc. > Malc (DBA, teaboy, scapegoat par excellence).
