Editing Engine:CCMD run (section)

== Examples ==
=== Default values ===
For a script file named 'startup.cfg' which looks like:
<kua>
echo fred
lua print(1 + 3)
alias bob fred
var fred james
bob
</kua>
* Try to load a non-existent file.
<kua>
> run bob.cfg
Run failed: bob.cfg
</kua>
* Run the example script file.
<kua>
> run startup.cfg
fred
4
'fred' is 'james'
</kua>
: In this case: echos 'fred' to console, runs a Lua statement that adds '1 + 3' and prints the result, creates an alias 'bob', creates 'fred' variable that the alias 'bob' will show the value of, runs the 'bob' alias that effectively prints the value of 'fred' that is 'james'.

=== Multiline strings ===
Strings in the base scripting language are intrinsically multiline.
* For a script file named 'startup.cfg' which looks like:
<kua>
echo 'fred
bob'

alias bob "
    lua run '
        local a = 5
        print(a + 1 + 3)
    '
"
bob
</kua>
* Run the example script file.
<kua>
> run startup.cfg
fred
bob
9
</kua>
: Here the echo prints across two lines. An alias is created with an embedded block of lua that runs via the 'lua' context 'run' command, which uses single quotes to not conflict with the outer double quotes. Then bob is run and the whole thing prints 9.
