• The set_char_pointer command can be used for referencing an indexed character. It
thereby becomes an indexed character that is protectable via
and/or callable via the index.
• set_char_pointer can also be used to reference anew an indexed subroutine, character
or text string so that it can also be called via a second index. Here, it is preferable to use
the copy_dst_src
• The start addresses of command lists that are to be referenced with set_char_pointer
can be queried via
• set_char_pointer only stores starting addresses in the internal management table. An
indexed character only gains protection via a subsequent
command.
• Pos should not be an arbitrary address within a list. Instead, it should be the starting
address of an actually existing subroutine that was finalized via
