The block circuit table (RUNGS) consists of a number of contiguous circuit definitions (RUNG), each of which contains all the information about a specific circuit and its contents.
The location (relative to the file) and the number of elements in the table are specified by the BLOCK.RUNGSOFF and BLOCK.RUNGSCNT fields, respectively.
