Re: Help with Klement's SMTP routines

Hello Thomas,

What do you mean by 'Convert error'?   Do you mean CPE3490 ("Conversion 
error")? That's the closest thing that I can think of to 'Convert error'.

This means that the document you're trying to either read or write to 
contains characters that cannot be translated using the to/from 
CCSIDs.   This happens a lot when you have a file with "garbage 
characters" in it, since they often contain bytes that don't correspond 
to valid code points in the CCSID you've selected.

You might also consider modernizing your approach.  Instead of doing two 
separate opens (open the file to create it, close it, then re-open it in 
text mode) you should rewrite the process to use O_TEXT_CREAT.   The 
method you're describing was normally used back in the old days for 
compatibility with V5R1 systems. Hopefully you don't need to be 
compatible with releases that old anymore?

For example, replace the two opens with something like this:

fd = open( filename
         : %bitor( O_CREAT: O_EXCL: O_WRONLY: O_INHERITMODE
                 : O_CCSID: O_TEXT_CREAT: O_TEXTDATA)
         : 0
         : 819
         : 0 );

if fd = -1;
  ReportError();
endif;

Good luck
