Customized contents using the SDATA parameter

The IBM-supplied default contents and the contents available through customization are detailed in Table 1. The tables show dump contents alphabetically by the parameters that specify the areas in the dumps. Before requesting a dump, decide what areas will be used to diagnose potential errors. Find the areas in the tables. The symbols in columns under the dump indicate how the area can be obtained in that dump; the order of the symbols is not important.
D
IBM-supplied default contents
M
Available on the macro that requests the dump
P
Available in the parmlib member that controls the dump options
X
Available on the CHNGDUMP operator command that changes the options for the dump type
blank
No symbol indicates that the area cannot be obtained.
Note: System operator commands and assembler macros use the parameters in the table to specify dump contents.
