How to print something in PL/SQL

When you use PL/SQL in SQL*Forms, you can show messages using the SQL*Forms MESSAGE() function.

I have built an SQL*Plus script, wich use in-line PL/SQL. My problem is that there is no way to print a message on the screen when you are inside the PL/SQL block! I wonder if someone have a solution for this. I can't understand why there is no ECHO, PRINT, TYPE, REMARK, COMMAND, MESSAGE or any such command that simply print-out a text string!
