Jim, I am not too sure about what you are doing here. So I am going to assume that the subfile display, display control, etc indicators are taken care of. you said if you write some dummy records, the subfile shows up. So I am thinking my assumption is right. When you have no records in a subfile, do not set the subfile display (SFLDSP) indicator on.You send a message saying "No records found" and display this message in the message subfile. Alternatively, you can define a dummy record which has nothing but a string that says "No records found" and write that dummy record first and then perform an EXFMT on the subfile control format with the subfile display indicator off. Hope this helps. -----Original Message----- From: Jim Langston [mailto:jimlangston@conexfreight.com] Sent: Wednesday, April 04, 2001 1:34 PM To: RPG400-L@midrange.com Subject: Simple Subfile question I don't work on subfiles too often, so this is really a simple question but... I am writing a new program and display file with a subfile. I loaded the subfile with dummy records and all is well. Now I am ready to read my real file, etc.. and I am displaying my screen for user input. Now I'm getting a session or device error, and I'm sure it's being caused by the subfile being empty. How do I display my subfile with empty records? Or do I have to check my SF_RecNum and only display it if it's not zero? *** Clear Subfile *** C Eval *IN55 = *On C Write SubCtl C Eval *IN55 = *Off C Eval SF_RecNum = *Zero C DoW NOT (*IN03 OR *IN12) *** Display Subfile and get input *** C Write Footer C Write Header C Exfmt SubCtl C EndDo bombs out on the Exfmt SubCtl with Session or device error occurred in file MNTSTGDFM (C G D F). However: *** Clear Subfile *** C Eval *IN55 = *On C Write SubCtl C Eval *IN55 = *Off C Eval SF_RecNum = *Zero *** Load some dummy records *** C Eval DFType = '* Test1 *' C Eval DFUnit = 100 C Eval DFSplt = 10 C Eval DFCuFt = 100.101 C Eval DFAmnt = 1000.01 C Eval SF_RecNum = SF_RecNum + 1 C Write SubFile C DoW NOT (*IN03 OR *IN12) *** Display Subfile and get input *** C Write Footer C Write Header C Exfmt SubCtl C EndDo works, but is obviously not what I want.
