====== READO.RECORD ======

==== Purpose ====

Used to read a record that will not be updated (read only). This code is provided for filing systems that might use buffers to store records already read.

In an MFS, this code is typically implemented in the same manner as a [[read_record|READ code]], with all arguments passed through to subsequent filing systems as if the code were [[read_record|READ.RECORD]].
