Bob, Sorry it just happened that I copied different already made codes and put them together to make this program. When I set and open the file I used the Err_Flag as my file descriptor. I have standardised Err_Flag as my file descriptor and tried the program again. The problem persist. -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx]On Behalf Of Bob Cozzi Sent: 10 November 2005 2:18 PM To: 'RPG programming on the AS400 / iSeries' Subject: RE: 3440:Operation not supported when trying to read an IFS file. When you open the file, you get a handle to that file back. You seem to be treating the handle only as an error code. You need to check the return value for <=0. Something like: Eval FileDescI = open('/myflie'... ) callp read(FileDescI : buffer : %size(buffer)... ) -Bob Cozzi www.RPGxTools.com RPG xTools - Enjoy programming again. -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx] On Behalf Of Emmanuel Zannis Sent: Thursday, November 10, 2005 7:55 AM To: RPG programming on the AS400 / iSeries Subject: RE: 3440:Operation not supported when trying to read an IFS file. Bob, I am following the examples in "Who knew you could do that with RPG IV" page 303 and pages 310 - 313. They don't store the value of FileDescI anywhere. Maybe I missing the plot. I have to say I am getting confused.

Emmanuel, Where are you storing the FileDescI value that you're sing on the read() function? I don't see you ever opening the file and saving the handle to that file in FileDescI. That is probably your problem. -Bob Cozzi www.RPGxTools.com RPG xTools - Enjoy programming again. -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx] On Behalf Of Emmanuel Zannis Sent: Thursday, November 10, 2005 7:03 AM To: rpg400-l@xxxxxxxxxxxx Subject: 3440:Operation not supported when trying to read an IFS file. List Hi, I still I can read my IFS file. I get the error 3440 (ENOTSUP 3440 Operation is not supported. EOPNOTSUPP 3440 Operation is not supported.). I am attaching a list of the program. I run the program in debug where I spotted the error. The path is passed as parameter: (/DIR/SUBDIR/FILE). The error occurs in line 123 attempting to read the file, nbytesread has a value of -1.
