SQL & PL/SQL

I am looking for a way to log sqlplus output from within a pl/sql procedure. When run through SQL*PLUS directly I can use SPOOL. Is there any way to do the same from within PL/SQL? Following is an example of what I was previously executing as a .sql script via command line SQLPLUS logon/password @instance @sqlscript.sql. Now I want to create a stored procedure to do the same...
Thanks,
Susan
