clear

 

 

Description

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).

When to use

The clear function is used to clear all of the data in the current workspace.

 

Syntax

(clear)



Name Description AIS Types
none none ---


Returns:

Always returns the Boolean value, true

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Context_clear_001

The clear function clears all global symbols whose Lock flags have not been set, effectively clearing the contents of the current Workspace.
