Comments • When interpreting the status values returned by read_status, always take into account
the programmed loading or execution processes of the lists.
Under some circumstances, the status values can be misleading, as illustrated by the
following examples:
– Even during a loading process, the
the
further list commands are loaded into the same list.
– The status values remain unchanged if a
command
– If – during a loading process– a
same list, then the list is regarded as already processed
though it is still newly loaded
– Even if a completely loaded command list (incl. set_end_of_list) has been stored,
the
example, by set_input_pointer) into the list. Then a list's
reset too, even though a completely loaded and already processed command list is
stored.
– For jumps from one list area to another ("List 1" <-> "List 2", for example, by
list_jump_pos) during execution, the
