Very weird - if I think of anything else I’ll holler.

Jon,

The file is 1252 (*PCASCII) and the IBM i job runs with 37. The file
starts out with X'0D0A' <CR> and <LF> at the end of each record. I don't
actually see the characters during debug when processing the file, but the
offset into data at various positions in the file includes two line ending
characters between data lines. It's when I write the file back these two
characters are simply changed to x'0D' <CR>.

I guess I could watch for x'0D'--EBCDIC <CR> and x'25'--EBCDIC <LF>. I
agree that I would have to code the appropriate hex values if I were
originating all the content, but I'm only reading a file which already
contains them. My understanding was the *PCASCII (code page 1252) x'0D0A'
would automatically translate to what I've assumed are EBCDIC (code page
37) x'0D25'. Then when writing the file back, they should automatically
translate back to *PCASCII x'0D0A'.

I could check the characters as the data lines are processed--they should
be x'0D25' and then make sure these are still there before rewriting the
data. But since I'm not touching these (i.e., simply moving them from the
input variable to the variable I use to write the data back), I'm not sure
how to make sure they aren't changed when I call the write API.

Any additional thoughts would be appreciated.

Thanks,

Re: Line-ending for IFS test stream file

I thought that if you were using o_TextData you had to code “your”
CRLF as being the appropriate hex values that will result in CRLF
post conversion. What values are you using and what is the target code
page?

Hi folks,

I've got a program which opens, reads, scans the data modifying some
of
the content, then writes and truncates a file in the IFS. It uses the
open, write, ftruncate, and close APIs. The open uses the o_TextData
flag
so the CCSIDs are automatically converted for my program to manipulate
the
data on the IBM i. Everything works great with the exception that the
line
ending carriage-return and line feed (CRLF) is being changed. When I
debug
the program and step through file scanning, the CRLF is being
processed
correctly--i.e., I see the two bytes processed at the end of each
line.
But when the file is re-written and closed, the CRLF is modified to
simply
be a carriage-return.

This isn't a problem most of the time, but there are cases where the
PC
program which later uses the processed data isn't recognizing the last

line of data since it doesn't end with CRLF. Is there an option I've
overlooked or something I can do to preserve the CRLF?

Thanks,
