Re: Weird error on IFS open()

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hi Jon,

You say the system CCSID is 37.  Can I assume that the job's code page 
is also 37?  The job CCSID is what is used when you specify 0, not the 
system's.

The manual states:

    If O_CCSID is not specified, and the file CCSID and open CCSID are
    not the same, and one of them is not strictly single-byte, open()
    will fail with errno set to [ECONVERT].

Since you aren't specifying O_CCSID, this COULD apply to you, but only 
if one of the CCSIDs is not strictly single byte.  819 is single byte. 
What about the codepage that corresponds to the job CCSID?

Another possibilty would be a bad prototype.  (I hope not!)  A bad 
prototype might mean that you're passing a codepage value that you don't 
expect to pass...

One wonders why you are using O_CODEPAGE to begin with?  Does this 
program need to work on V4R5 or earlier?
