Description

Delete a Decision in ExtDecBuffer deletes a decision from the decision buffer. If two or more decisions are in buffer with same name, the first decision with that name is deleted. If no decision are found with the name an error is generated.

The difference between Delete at a Decision in ExtDecBuffer and Delete a Decision in ExtDecBuffer is that the former takes the offset; the latter takes the name.

Example

The following are the decisions.

Offset	Name
1	Decision Left
2	Decision Right
3	Decision Up
4	Decision Down

Delete a Decision in ExtDecBuffer would take Decision Right as a parameter.

Delete at a Decision in ExtDecBuffer would take the offset 2 as the parameter.
