Identical sets

[Gabriela G.]

I want to know if its possible to create a subset identical to the root set and then, inside a procedure delete certain elements of said subset.

Yes, you can.

The statement would be

Subset := Subset - {index | condition on index}

All the elements that meet the "condition on index" will be removed from the subset.

You can also use

Subset -= element_parameter;

or

Subset -= 'element';

-= is another way of writing Subset := Subset -
