You can use the IBM-provided IFG0199I installation exit to recover from abend situations caused by tape positioning errors. They might occur during the opening, closing, or processing of an end-of-volume condition for a non-VSAM data set associated with your application program.

The exit might need to examine the DCB, DCBE or DEB to ensure that fields were used correctly for the type of data set. For mappings of the DCB and DCBE fields, see z/OS DFSMS Macro Instructions for Data Sets. For mappings of the DEB fields, see z/OS DFSMSdfp Advanced Services.
