The @ instruction ends the program. Some interpreters revert changes to the code (made by p) while others do not.

<code>•Exit</code> immediately terminates the running BQN process. If the argument is a valid return code (on Unix, an integer), it is returned; otherwise, the default return code (the one returned when the end of the program is reached) is used.
We can use a block to create a conditional exit. Here we exit if the script is given zero command line arguments:
<syntaxhighlight lang="bqn">{
0=≠•args ? •Exit 0;
•Show "has args"
}</syntaxhighlight>
