Thank you very much in advance! Whenever something works on the command line and not in cron, suspect the environment. All cron-run jobs have an utterly minimal environment -- typically, PATH, HOME, LOGNAME perhaps, and that's it. Occasionally, you get one or two other random variables, such as HZ. Most probably, the ontape is failing because the Informix environment is not set. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
