NAB-Type Files with Fixed-Length Items

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:

  1. This figure shows a file ('PO') which contains a field called yyyyINX.

  2. yyyyINX contains a next available byte (NAB) pointer, which defines where the last item in the block is located.

  3. The items have a fixed-length, and each contain a reference to a 'PR' block.

  4. The reference is in an item, so the ID2 parameter is specified.
