Report field description

The report fields are as follows:

DBNAME DB# DSG# DSNAME
The name of the DBD, the database number (in hexadecimal), the data set group number (in hexadecimal), and the name of the data set
SOURCE
The segment that contains the pointer (also called the source of the pointer). The following four fields all pertain to it:
DB
The database number (in hexadecimal) that identifies the database containing the segment that contains the pointer
DG
The data set group number (in hexadecimal) that identifies the database containing the segment that contains the pointer
SC
The segment code (in hexadecimal) of the segment that contains the pointer
SEGNAME
The segment name, as coded in the SEGM macro in the DBD, of the segment that is the target of a pointer
PTR
The type of pointer such as LP, LTF, LTB, LCF, and LCL
TARGET
The target of a pointer. The following four fields all pertain to it:
DB
The database number (in hexadecimal) that identifies the database containing the target of a pointer
DG
The data set group number (in hexadecimal) that identifies the database containing the target of a pointer
SC
The segment code (in hexadecimal) of the target of a pointer
SEGNAME
The segment name, as coded in the SEGM macro in the DBD, of the segment that is the target of a pointer
EXTERNAL
The number of pointers that point to another data set
