Workmod data elements

Module data in the binder internal (workmod) format is organized into units called elements. (Some older or obsolete binder documentation may call these 'items' or even 'itemids'). An element is identified by a section name and class name.

The formatted portion of the dump provides the information necessary to find the data associated with each element in each workmod (see Figure 1 for an example). The data is formatted in a three-level hierarchy as follows:

workmod
section
class

The first line output for each element prints:

APPPTR: The pointer to the first "append pointer" - that is, to the control block describing the first block of contiguous data in the element.
CNT: The append count (the total number of such contiguous blocks).
HIW: "HI-WATER" - the highest record number in the element. For text, this is the last byte of initialized text - it may be smaller than the total CSECT text length.
LRECL: Length of one logical record

In the second line for each element, 20 bytes of attribute information are shown. The first two fields give the offset of the data within the containing class and the length, relative to records. (For text, the length of one record is one byte.)
