Re: IFS I-O Problems

Jeff, take a look at the docs for open() - when the return code is -1, there is a variable called errno that has another number in it. These are listed at the bottom of the documentation. You can find these also in a source member ERRNO in QSYSINC/H. You might want to make constants in a /copy member for the values you expect to encounter.
There are system messages with more info - CPExxxx where xxxx is the value of errno can be displayed. (Learned this on this list!) E.g., for errno=3009 

Message ID . . . . . . . . . :   CPE3009
Message file . . . . . . . . :   QCPFMSG
  Library  . . . . . . . . . :     QSYS

Message . . . . :   File is not opened for write operations.
Cause . . . . . :   You tried to update a file that has not been opened for
  write operations.
Recovery  . . . :   Open the file to allow writes and try your operation
  again.

I am using the IFS IO API's and am having a problem creating a file in an RPG IV program. 
I am getting back a -1 in the File Descriptor when using the OPEN.
My file name is \root\ifsreports\JEFF\corbtch.xls, Open_Flag is O_CREAT + O_WRONLY + O_CODEPAGE, Mode_Flag is S_IWUSR + S_IRUSR + S_IRGRP + S_IROTH. 
Is there any way to determine what it does not like?
