== Examples ==
=== Default values ===
<kua>
> bob
Unknown: bob
</kua>
No 'bob' in the context. Variable 'bob' doesn't exist, and 'bob' is not the name of anything else.

<kua>
> bob fred
Unknown: bob
</kua>
Tries to set variable 'bob' to 'fred'. Fails as 'bob' does not exist.

<kua>
> set bob fred
</kua>
Uses the 'set' command to create the variable 'bob' and set value to 'fred'.

<kua>
> bob
'bob' is 'fred'
</kua>
Same as the first example, but now 'bob' exists.

<kua>
> bob james
> bob
'bob' is 'james'
</kua>
Tries to set existing 'bob' to 'james', value changes.

=== Change if exists ===
In this example let's pretend 'bob' is a Client module variable. Client when started will create 'bob' with a default value in the 'global' context.
*  Variable 'bob' doesn't exist, and 'bob' is not the name of anything else.
<kua>
> bob
Unknown: bob
</kua>
* Tries to set variable 'bob' to 'fred'. Fails as 'bob' does not exist. Which is good.
<kua>
> bob fred
Unknown: bob
</kua>
* Using the 'client' context run the Client 'start' command which will create the variable 'bob' with a default value of '8080'. 
<kua>
> client start
</kua>
* Same as the first example, but now 'bob' exists.  
<kua>
> bob
'bob' is '8080'
</kua>
* Try to set existing 'bob' to '8081', value changes. 
<kua>
> bob 8081
> bob
'bob' is '8081'
</kua>
=== Macro ===
In this example 'bob' is still a Client module variable. We want to check the old value of bob before restarting the client. 

* Check the value of bob. Stop the service. Then start client and then change the value after started. Client was not started previously.
<kua>
> bob; client stop; client start; bob 8081; bob
Unknown: bob
Client not started.
Client started.
8081
</kua>
* Same but Client fails to start, and removed or did not yet create the variable 'bob' before returning.
<kua>
> bob; client stop; client start; bob 8081; bob
Unknown: bob
Client not started.
Client could not start.
Unknown: bob
Unknown: bob
</kua>
