=========================================                                       
Despite creating a KSAM64 file with the REUSE option, it is still               
possible that, over time, the file will fill up and still contain               
deleted records.  Fwrite to the file results in END OF FILE (FSERR 0).          
                                                                                
There is a defect in the management of the deleted records which can            
result in them not being reused.  This problem happens when records             
are deleted from a KSAM64 file.                                                 
                                                                                
This patch corrects the problem.  Note that since this problem is in            
the delete (fremove) operation, the installation of this patch will not         
recover the space from KSAM64 files which is already lost.  They will           
need to be unloaded, rebuilt and reloaded.

TurboImage versions C.10.00 and later use KSAM64 files for B-tree               
indexes.  It is recommended that this patch be installed on all                 
systems that use this version of TurboImage and B-tree indexes.
