11-114 Eight 13-byte groups of processor status data, one group for each of eight possible controllers on the loop. If a particular controller on the loop is
not active or does not respond to the diagnostic status command, its 13 status bytes will be all zeros. Otherwise, each group of processor status
bytes will contain the following:
Byte 1 Program ID
2 Processor ID
3 Pointer to Start Program
4 Pointer to End of Available Memory
5 Size of I/O
6 Processor Error Code
7 Error Word Address (Low Byte)
8 Error Word Address (High Byte)
9 Processor Mode
10 Pointer to END Statement (Low Byte)
11 Pointer to END Statement (High Byte)
12 Pointer to End of Used Memory (Low Byte)
13 Pointer to End of Used Memory (High Byte)
