Classification : Internal VB Data Set Considerations Starting Positions For FB data sets, the first data byte starts in position 1. However, for VB data sets, the Control Field is in positions 1-4, so the first data byte starts in position 5. Short Control Fields If you know you have VB records with short control fields, you can specify the VLSHRT option, if appropriate, to prevent DFSORT from terminating OPTION VLSHRT
