User Defined Table Function (UDTF)

I am attempting to create a user defined table function which returns a
table structure defined at run-time. I have a function that works;
returning a comma separated list of fields in a single varchar field
(see below). This is not ideal for my needs.

I am unable to find any documentation on how to create a table structure
at run-time; does anyone have any pointers or examples?


Current Function Creation:

Create Function JEHIMES1/RMTTBL (datain char(10))
Returns Table( DATFLD varchar (3200) )                                 
External Name 'JEHIMES1/RMTTBLM(PROCESSLIST)'  
Language RPGLE                                 
Disallow Parallel                              
No SQL                                         
Parameter Style DB2SQL                         
Not Deterministic  

Thanks,
