Main Storage Dump Labels

Table 40 lists the labels found in main storage dumps to identify the storage locations of various TPF tables and work areas. The table columns have the following meanings:

Column Heading
Description

 Label 
Identifies the label in the dump.

 References 
Identifies the corresponding DSECT, CINFC label, and control program (CP) label for the dump where relevant.

 Scope 
Indicates whether the label is unique for a system (S), a subsystem (SS), a subsystem user (SSU), or an I-stream (IS). For example, if a dump label is unique for a SS, there is one dump label for each SS. Therefore, SS is printed in the Scope column for that dump label.

 Description 
Explains the dump output marked by the label.
