Right, if I execute the command as a browser request I get a "CGI Error"
message instead of an image.  If, using the command line, I force the output
to a file I can see the garbled images I attached earlier... but only in
certain image programs.  Most software will crash when trying to open the
image. 

So I suppose some output is created, but it isn't anything usable.

This latest debug experience is my first brush with command line Mapserver
as well.  It brings up some intriguing possibilities for quasi-dynamic map
production... perhaps map creation triggered by system events, like data
downloads...

Thanks again for the help!

Mike,

I've never seen this done on the command line.  It opens up a whole new box
for me.

You wrote that it failed but that you still got an image back.  I don't get
it.  Which is it?

Like Mr. Ramsey suggests, when you just typed
'//rpw-edms/crrel/usartrak/test.map&mode=map' in the browser address bar you
get a cgi failure, right?

Sure, in the mapserv.exe directory I ran the following commands: 
set "REQUEST_METHOD=GET" 
set "QUERY_STRING=map=//rpw-edms/crrel/usartrak/test.map&mode=map" 
mapserv.exe > c:\inetpub\scripts\test.gif 
This produced the image I sent out. 
-btw tried again with interlace set to OFF in the map file, still failed but
the resulting image looked a little different. (attached)
My relationship with the all powerful Essree has also been somewhat
love-hate lately.  Our web mapping tools are some of the last remaining
non-esri technologies we use, unfortunately.

Hey, saw my name and I figured I'd give it another shot, especially with my 
long-standing love-hate relationship with E.S.R.I. 
Can you send us your command line request?

Pardon my reply to my own post, but I am starting to run out of ideas.  
I generated a test image (attached) from a map file containing two layers 
using the command line.  
It is viewable in Internet Explorer but all my other image software reports 
an error when opening it.  Has anyone had issues with the .dll's included 
with the 4.2 binary?  I am pretty confidant they aren't the problem, but at 
this point I am grasping at straws. 
Any and all assistance is greatly appreciated, unfortunately this is a 
make-or-break project for Mapserver within the U.S. Army Alaska.  If I can't

resolve my issues, it will be a big the foot-in-the-door for the ArcIMS 
camp.
