Figure 70 shows an example of the DBDEF statements to describe a
NAB-type file with fixed-length items.
Figure 70. NAB-Type File with Fixed-Length Items (CBV=1)
Notes:
- This figure shows a file ('PO') which contains a field called
yyyyINX.
- yyyyINX contains a next available byte (NAB) pointer, which defines where
the last item in the block is located.
- The items have a fixed-length, and each contain a reference to a
'PR' block.
- The reference is in an item, so the ID2 parameter is specified.
