Dispatcher resource record (DIS - Type 3E)
In this record, for field names that end with nnn (such as DISTN nnn ), up to 18 different TCB Pool statistics areas (001 through 018) are available. The actual number is provided in the DISASIZE field.
For the field names that end with XXn (such as DISPNXXn), up to 4 TCB Pools (XX1 through XX4) are available. The actual number is provided in the DISPSIZE field. \
