Yes, Booth. This is the part that writes the headers:

CharVar = 'Status: ' + %char(httpStatus) + CRLF
+ 'Content-type: text/plain' + CRLF
QtmhWrStout( charVar : %len(charVar): err );

Headers in a CGI program (which really all this is) are written out
followed by 2 CRLFs to show the end of the headers. All data (JSON, XML,
HTML, etc) follows that.

The QtmhWrStout is the API that writes to Standard Output. I believe your
program should already be doing this for your JSON data. This is a part
that is normally made easier by toolkits like CGIDEV2 and the eRPG SDK.
Also things like reading input, parsing data, etc are done behind the
scenes in a much easier fashion that using the APIs. But, I still think
it's a good idea to have a high level understanding of what is going on in
the background.

This may be a good 2-6 bucks to spend to learn the basics of CGI

You can ignore the chapters on HTTP server setup since it's based on the
old CERN web server. But the rest should still be very pertinent. I hear
it's a good read. :)

OK. I wrote my program using JSONWEBSRV from your tutorial as the
model. Is that the program that writes headers, then a blank line, then
the data?

A2: When you write programs like this (called via the CGI interface
from Apache) you must write headers, then an empty line, then the
data. This error means that it never found the blank line that ends
the headers. Most common reasons are (a) its not getting written at
all, (b) you've forgotten to include the headers (c) you've forgotten
to include the blank line that tells it about the end of the headers
or (d) you're writing in the wrong character set so it doesn't
understand it.
