Heap pool report sections of the LEDATA output

As Table 1 shows, the heap pool report provides information about the following items:

Each cell pool.
The free chain associated with every qpcb pool data area, and all the free and allocated cells in the extent chain.
Errors found when the cells are validated.

Table 1. Contents of the heap pool report sections of the LEDATA output (AMODE 64)
Section Number and Heading	Contents
[1] Free Chain Validation	Within each cell pool, Language Environment keeps track of unallocated cells by chaining them together. The LEDATA HEAP option validates the free chain within each cell pool. It verifies that the cell pointer is within a valid extent and that the cell pool number is valid. If the formatter finds a problem, it will place an error message describing the problem directly after the formatted line of the cell that failed validation.
[2] Heap Pool Extent Mapping Report	The LEDATA HEAP option produces a report that lists all of the cells within each pool extent, and identifies the cells as either allocated or freed. For each allocated cell, the contents of the first X'20' bytes of the area are displayed to identify the reason for the storage allocation. The formatter validates if the cell pool number in header is correct.
