Very Small Numbers and 4gl

We have an application which needs to unload data from tables based on certain runtime selection criteria. When run as an unload statement from dbaccess (we are running SE 5.01) all of the data unloads but one of the float fields has a very small number 1.????e-269 in it. The same unload statement from 4gl unloads everything up to the row before the row with the bad data. Is this a known bug? Do I need to run a routine check on the data each night to correct this problem? Any ideas what might be causing this problem? For all rows where this problem exists, the very small number is the same. The rows were inserted on different days and in some case a re-ipl of the system had been performed. Any ideas and suggestions will be most appreciated. Thanks in advance. -- Jay Falck jfalck@eden.com Unix System Administrator jfalck@access.texas.gov Central Reservation Center 512-389-8962 Texas Parks & Wildlife Dept 512-389-8998 (Fax)
