Directed Access

The directed access method of selecting the data entry to be read requires that you specify

the record number of that entry. Record numbers are returned in status halfwords 3-4 by a

successful call to the TurboIMAGE/XL intrinsic DBPUT (refer to the discussion of DBPUT in

chapter 5). Other numbers that can be used for directed reads are the forward and

backward pointers returned in status halfwords 7-8 and 9-10. To use these numbers for

directed reads, you need to save them because subsequent TurboIMAGE/XL procedure

calls can overwrite the status area.
