Ctrl Command set_sub_pointer
Function stores the absolute start address of a command list in the internal management table for
indexed subroutines.
Call
set_sub_pointer( Index, Pos )
Parameters
Index
Pos
Comments • If Index > 1023 and/or Pos > (2

• The set_sub_pointer command can be used for referencing a nonindexed subroutine,
which thereby becomes an indexed subroutine that is protectable via
save_disk/load_disk
• set_sub_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_sub_pointer
can be queried via
• set_sub_pointer only stores starting addresses in the internal management table. An
indexed subroutine 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
not contain set_end_of_list.
