VARKON Version 1.15 1997-10-24
Sets the root position in GM
Description
Used to move the current root position in the GM hierarchy. This routine is intended for
use together with get_next_gm when traversing the contents in GM. With set_root_gm
traversals can be restricted to only a specific part or subhierarchy. This can save lots
of time if GM is large.
Syntax
set_root_gm(part_id)
| REF | part_id; |
Principal parameters
None.
Optional parameters
| part_id | - Global identity of part to act as the new root. If not specified the root is set to the top of GM |
Examples
set_root_gm(#5#3)
Makes the part #5#3 become the new root position in GM. Consecutive calls to GET_NEXT_GM
will only return entities from the subtree belonging to #5#3.
set_root_gm() or set_root_gm(#0)
Resets the root to the absolute top of the entire GM. This is also default when a new job
is started.
