An empty file is a valid program.
=={{header|Binary Lambda Calculus}}==
At 4 bits, or half a byte, the smallest BLC program is `cat' :
<pre>00 10</pre>
corresponding to the smallest valid lambda term, the identity function \x.x

Line 330 ⟶ 338:
Pressing enter from the mged prompt, just returns another prompt, so I suppose that is the smallest possible program. However, before we can draw anything we at least need to open a database:
<syntaxhighlight lang="mged">opendb empty.g y</syntaxhighlight>
=={{header|Bruijn}}==
The smallest program in bruijn is the identity function (\x.x) and returns its input:
<syntaxhighlight>main [0]</syntaxhighlight>

This is equivalent to:

'''Solution'''
The following is the simplest expression: the Null expression. When it is run, it does not reduce to anything else, because there should not be rewriting rules for a null expression:
