NBS_FIND_ITEM

Find an item with a specified name contained in a structure associated with a specified identifier and return the located item’s ID

Description:

Check that the environment ID is not NIL and does not pertain to a primitive item.
Search for an item of the required name (don’t assume that they are in any particular order).

The searching is performed using a binary search. This means that it takes roughly the same time to find all the items — best case performance is degraded but worst case performance is substantially improved.
