delete

Remove instrument objects from memory

Syntax

Arguments

obj
An instrument object or an array of instrument objects.

Description

delete(obj) removes obj from memory.

Remarks

When you delete obj, it becomes an invalid object. Since you cannot connect an invalid object to the instrument, you should remove it from the workspace with the clear command. If multiple references to obj exist in the workspace, then deleting one reference invalidates the remaining references.

If you attempt to delete obj while it is connected to the instrument, then an error is returned. A connected object has a Status property value of open. You can disconnect obj from the instrument with the fclose function.

Example

This example creates the GPIB object g, connects g to the instrument, writes and reads text data, disconnects g, removes g from memory using delete, and then removes g from the workspace using clear.
