CR 2CRLF

[Kathy Riggle]

I’m trying to change carriage return (after segment) to carriage return-line feed. I have a script that partially works. It works fine for between segments. However, since the end of the message already has CR-LF, I am getting CR-CR-LF at the end of each message.

 run {

           # ‘run’ mode always has a MSGID; fetch and process it

           keylget args MSGID mh

           set msg [msgget $mh]

           # substitute all with

           regsub -all “r” $msg “rn” msg

           msgset $mh $msg

           lappend dispList “CONTINUE $mh”

       }

Is there a better way to do this?

Kathy,

 I had to do something similiar. I was having to ftp a file and the receiving system need n after each segment. I used string map to do that.

set msg [string map {r n} $msg]

What are you doing with the message after you are done.  Is it being ftp’d, sent to another system via tcp/ip..etc

John,

I put something similar in place as an OB tps. It worked between the segments, but I ended up with an extra CR at the end of each message.

We do ftp the file to our financial system, where it choked on the extra CR.

Kathy,

I guess you could always add one more string map (or regsub – your preference) to substitute /r/n for /r/r/n after your intitial substitution.

Hi Kathy,

I’ve taken your script verbatim and run it through my tester (5.2).  I don’t get the same results you are getting.  When I run it through the tester, it changes the r between the segments to rn and leaves the rn at the end of the message as is.

One possible solution to your problem may be to simply take the “msg” variable and do a split on it and then do a join right after.

set segs [split $msg r]

set new_msg [join $segs rn]

Maybe Jim can confirm but wouldn’t that only touch the ones between the segments?

Let me know if you get it working.

Thanks…Tom

Kathy,

 Are you using cloverleafs. FTP protocal? We write it to a file manually in a tps using the puts with the nonewline option as they wanted some really weird formatting other then the newlines for each segments.  We then use a cronjob to ftp the file.  The different protocols add there own delimiters when it writes it out.  I’m suspecting that might be where you are getting it from.  This is assuming that you are using the FTP protocal but try setting your outbound style of the FTP protocal configuration to eof.  The way I read it, it should right the message with no delimiter as it assumes the OS will write the eof to the file.

Hope this helps,

John

I really should proofread more when I have a migraine. 😳

It is truly embarrassing when you miss the most obvious of answers!  😳

My regsub script was working OK — my protocol was wrong. Yep, John, you hit it right. I was adding the nl there, instead of using the eof protocol. DUH!

Thanks everybody! 😀
