Re: Subfile Examples

     Gade,
     
     Message subfiles are trivial - if you have more than four lines of 
     code to manage a message subfile, you are overcomplicating it.
     
     As Buck already posted, check your program design to see why the 
     subfile is slow.  As a rough rule of thumb, you should only read about 
     the same number of records as are in the subfile page.  If the design 
     is such that the number of I/Os required exceeds the page size by 
     orders of magnitude, you get performance issues.
     
     One final note - I don't know if this is still an issue, but it used 
     to be that on a remote terminal (5292?) you could greatly improve 
     performance by always writing the display top-to-bottom.  In other 
     words, writing the message subfile, then the function key line, then 
     the subfile, caused slow screen redraws.  Anyone know if this is still 
     the case (with telnet, say)?

Hi Guys,
     
I feel like my subfile is running really really slow. Could somebody give 
me a good example for subfile & message subfile programming in RPGIV where 
subfile page = size??.
     
What are the modern ways of populating the subfiles in ILE RPG???.
     
Thanks.
Gade.
