Example Structure remove 001

 

 

Description

This example defines a Structure and uses the remove function to non-destructively delete a key-value binding by specified the Structure key. If the key does not exist in the Structure then the same Structure is returned unchanged.

 

Details

(setq Z #{A: "Now" B: "is" C: "the" D: "Time"} ) Returns: #<Structure 123456>

Removes the key-value binding with key D: and copies the result to a new Structure.

(setq A (remove D: Z)) Returns: #<Structure 234567>

Displays the modified Structure

(display A) Returns: #{A: "Now" B: "is" C: "the" }

The original Structure still remains unchanged.

(display Z) Returns: #{A: "Now" B: "is" C: "the" D: "Time"}

The key F: is not found in Stucture Z.

(setq A (remove F: Z)) Returns: #<Structure 345678>

If the key is no found, he original Structure remains unchanged.

(display Z) Returns: #{A: "Now" B: "is" C: "the" D: "Time"}
