RE: Problem with QtmhCvtDb API

[rgh@xxxxxxxxxx]

It is important to remember CGI programs that read data from the standard
input stream, only CONTENT_LENGTH bytes should be read from standard input.
Attempts to read more than CONTENT_LENGTH bytes produces unpredictable
results.   In this case, you have 0D25.

In the technical studio on the AS/400 web page there are some RPG snippets
that will convert the character CONTENT_LENGTH to decimal to be used as the
number of bytes to read parameter for QtmhRdStIn.

When the last field is numeric and you read more bytes than CONTENT_LENGTH,
you will get a -4 RC from QtmhCvtDb.   Your other application is working
because the last field is character and the CRLF are just characters and
not invalid for character data.    Although they would probably be invalid
if you used the data as a search parameter.

I just found another peculiarity.

It's throwing a hex '0D25' at the end of my data (I'm guessing CRLF).
Should it be doing this?  Could this be causing a problem or are these the
delimiter characters that it uses to signal the end of the data stream?
