Answer / s
PTR=TB to suppress the RAPS to improve sequential
processing.
If PTR=T or PTR=H is specified, only RAP is created per
CI/block and the RAP points to the last root segment
inserted and the hierarchic or physical twin pointers will
point to the previous root segment inserted and the
hierarchic or TF pointer in the first root is set to zero.
This means that the HIDAM index has to used to process
roots sequentially as the pointer from one root to another
cannot be used.
