Stored procedure table dependency list

Hi all, Is there a way via system catalog tables to see a stored procedure's table dependency list? The sysprocplan table encodes the dependency list, but is there a way to see the un-encoded list? I did find Sujit Pal's Perl script (FAQ) for building the column and table dependency list which looks useful, but was just wondering if there's another way to determine the list via system catalog tables. Maybe an "un-encode" function would be helpful. Thanks Steve
