'bob' without a value. Variable 'bob' doesn't exist, and 'bob' is not the name of anything else. | |||
<kua> | <kua> | ||
> bob fred | > bob fred | ||
Unknown: bob | Unknown: bob | ||
</kua> | </kua> | ||
Tries to set variable 'bob' to 'fred'. Fails as 'bob' does not exist. | |||
<kua> | <kua> | ||
> set bob fred | > set bob fred | ||
</kua> | </kua> | ||
Using the 'set' command to create the variable 'bob' and set to 'fred'. | |||
<kua> | <kua> | ||
> bob | > bob | ||
'bob' is 'fred' | 'bob' is 'fred' | ||
</kua> | </kua> | ||
Same as the first example, but now 'bob' exists. | |||
