Exception data sections
The exception data section contains a single exception record representing one
exception condition.
The format of an exception data record (including the SMF header and SMF
product section) is shown in Figure 115.
The format of the exception data section can be mapped by the DSECT
MNEXCDS, which you can generate using the DFHMNEXC macro as follows:
MNEXCDS DFHMNEXC PREFIX=EXC
The label ‘MNEXCDS’ is the default DSECT name, and EXC is the default PREFIX
value, so you could also generate the DSECT simply by coding
DFHMNEXC
The MNEXCDS DSECT has the format shown in Figure 116 on page 765.
