Pete,

I think you need to close the file after creating it then open it again
for output something like this:

fd = open('/ads2datanfs/ads001.txt':
O_CREAT+O_WRONLY+O_CODEPAGE+O_APPEND:
S_IWUSR+S_IRUSR+S_IRGRP+S_IROTH:
437);
callp close(fd);
fd = open('/ads2datanfs/ads001.txt':
O_WRONLY+O_TEXTDATA+O_APPEND);

I've been bitten by that too. The conversion map is instantiated based
on the CCSID of the output file, so you must open it twice. You could
create it with "touch -C 819" to achieve the same result. There is
another newer constant available for the open bitmap that is supposed to
allow you to write correctly with a single open, but I've not used it. I
think I found the double open info in one of Scott's articles when I was
fighting with it. Like most things, it's really easy once you figure it out.
