Moving elements between mark IDs

Altair Forum User

Hi,

 

Is it possible to move elements present one mark ID to another without deleting the elements already present in the former mark ID ? I have elements in two diff mark IDs and I need to make use of both sets of elements by referring only one mark ID.

Hi,

I do not clearly understand your mind... /emoticons/default_rolleyes.gif' title=':rolleyes:'>

 

If you have some elems in mark 1, and you want to move it to mark 2, you can do:

eval *createmark elems 2 [hm_getmark elems 1]

 

mark 1 still stores those elems. so the two marks are equal

 

 

But I think you are in this scene:

- you have some elems in mark 1, and some others in mark 2

- you want to do some tasks need mark 1 but want to remember elems in mark 1, too

There are several ways without affect to mark 2

1) you can store elems in mark 1 into a variable and restore them later, forexample

set ElemList1 [hm_getmark elems 1]

# do something using mark 1

...

#restore mark 1:
eval *createmark elems 1 $ElemList1

 

2) store elems in mark 1 into usermark, then restore later:

*marktousermark elems 1

#  do something using mark 1

...

#restore mark 1:

*createmark elems 1 retrieve

 

3) store elems in mark 1 into a table, then restore later:

hm_marktotable elems 1 elem_table_name

#  do something using mark 1

...

#restore mark 1:

hm_tabletomark elem_table_name 1

hm_tableclear elem_table_name ; #free memory

 

If you are manipulating on many mark, moving to table is good choice. It's fast, and you can do intersection, union, cut, remove same with mark
