To support the enhancements to function string processing, Replication Server 15.5 extends the rs_helpfstring and rs_helpclassfstring stored procedures:
rs_helpfstring – displays function strings for table-level functions and displays those without output commands
rs_helpclassfstring – displays function strings for class-level functions and those without output commands
See Chapter 6, “Adaptive Server Stored Procedures” in the Replication Server Reference Manual.
