sub_id1 sub_id1 specifies a subunit that variables will be
traced in. sub_id1 is specified by [SUB] sub_id or
MAIN.
sub_id3 Each sub_id3 specifies an additional subunit that
variables will be traced in. Each sub_id3 is specified
by [SUB] sub_id or MAIN.
sub_id2 sub_id2 specifies a subunit that variables will no
longer be traced in. sub_id is specified by [SUB]
sub_id or MAIN.
sub_id4 Each sub_id4 specifies an addition subunit that
