The ''BYTES'' command returns the size in bytes of an object and its [[https://en.wikipedia.org/wiki/Cyclic_redundancy_check|CRC32]] checksum as a base-16 integer.
</callout>

<callout type="warning" icon="true" title="Compatibility">
----
''BYTES'' is not fully equivalent to its **userRPL** counterpart.

In particular:

  * the algorithm used in **userRPL** is different.
