This can be done in RPG, but only by prototyping and wrappering the C  
record I/O procedures.  This is not that hard, but does require a  
certain amount of knowledge of C.  I thought that there were some  
examples of doing this out on the web but I don't have time to search  
for them right now.

An alternative option is the use the Dynamic Screen Manager (DSM) APIs  
to handle the screens.  This will not strictly speaking give you a  
subfile but can be used for scrolling lists in windows etc.  Again  
there are examples out there.
