Hello and welcome to the forum,
sysdump information is collection of all hexadecimal codes so we cant understand what the data it is
Actually, quite the opposite. . .
A dump is where the truth can be found. . . It is not magic. It is the contents of the storage where the problem code was running.
and this inf is stored in various registers ..
Unfortunately, no, it isn't. While registers are used heavily in processing mainframe programs, the majority (over 99%) of the data is not in a register at any given moment.
