3.6.3 DSECT mapping
By using the DSECT command from within the interactive report, storage ares can be
mapped based on PDS(E) data set members containing assembler macro DSECT copybook.
Figure 3-64 shows a copybook describing the DSA. We will map this copybook in the next
steps below, over the DSA storage area in a dump.

136 Using IBM Application Development Tools for z/OS and OS/390
In the point of failure section in the interactive report, we place the cursor at the address of
R13, which points to DSA, as shown in Figure 3-65, and press Enter.
Figure 3-65 Address selected
DSA storage is now shown, and we place the cursor at address 0D284030, as shown in
Figure 3-66
. Next, press PF4.

Figure 3-66 DSA before mapping
The Storage DSECT Mapping panel displays, and we fill in the DSN where the copybook is,
in this case SHARKMN.IDIDSECT(DSA), as shown in Figure 3-67. Next, press Enter and the DSA
is mapped with the copybook as shown in Figure 3-68.
