I'm doing the LF to blank in the C code -- have a library routine to do that
already, so just as easy as tr.

I don't think I need to. Here is my "flowed" output. I think plenty readable
enough. Picture this as part of a mainframey message XYZ0123E Error blah blah
TCPIP JRConnTCBNotFound: A TCB was not found for the specified socket.
Action: Use a valid socket descriptor.
or
TCPIP JROK: The return code value describes the error Action: Refer to the
return code for information on the error.
Ah! pclose(). Got it. I was using fclose() but I see I have a potential timing
issue there, and pclose() is where I where I would get an error status from. I
will try it with a command of bpxmfoo and see if I can detect the error.
Thanks for your help, @Gil and all. It takes a friggin' village to wade through
the IBM documentation.

Silly me! If you intend to get status from pclose(), leave out the "| tr ...".
You'd get the status from tr, which hardly ever fails.
How do you tell original line feeds from original blanks so everything
doesn't just flow together?
