CLEAR opcode is used to set a data item i.e. a field with
predefined default value based on its type. This opcode is
particularly useful when it specified for a data structure
because it clears all of the subfields in the data
structure.
char = *blanks Numeric = 0 etc
RESET is returns a filed to its intial value as specified
in INZ keyword.
