specified in the COUNT operand is not exceeded before this time interval
elapses, the error count is reset to 0. Specify “units” as SEC, MIN, or HRS. The
maximum values for “interval” are as follows: (86400,SEC), (1440,MIN), or
(24,HRS). This operand is optional, and the default is set to (7,MIN).

Node Error Block: The table contains node error blocks that are used for recording
error information for individual nodes. These can be permanently assigned to
specific nodes or dynamically assigned at the request of error processors.

Common Subroutine Vector Table: The CSVT provides error processors with
addressability to the common subroutines. The error processor link register gives
addressability to the CSVT and so the first section of the DSECT overlies the code
required to branch around the actual table.
