The OB methods table (OBMETHODS) consists of a number of contiguous (OBMETHOD) definitions, each of which contains all the information about a specific OB method related to the OB class to which it belongs.
The location (relative to the file) and the number of elements in the table are specified by the OBCLASS.METHODSOFF and OBCLASS.METHODSCNT fields, respectively.

(#1) The value of the CALLID field is derived from the value of the METHOD.ID field, in the source .OBB file.
Parameter table for OB method
The parameter table by OB method (OBMETHODPS) consists of a number of contiguous definitions (OBMETHODP), each of which contains all the information about a specific parameter related to the OB method to which it belongs.
The location (relative to the file) and the number of elements in the table are specified by the OBMETHOD.PARAMSOFF and OBMETHOD.PARAMSCNT fields, respectively.
Parameter definition for OB method
