Overview

The clear function clears the current contents of RAM memory also known as the Workspace. The clear function will not clear global variables whose Lock Flag is set (see the lock function).

ObjectRepository

The clear function erases the specified ObjectRepository database archive file {aGor} and forgets all objects saved in the ObjectRepository. An ObjectRepository, which has been cleared, is now empty, and may immediately be used to store new objects if desired.
