RE: More on Command Line and Run Arugments

Thank you Peter for you response to my query.  Because of it I reread
what I wrote and having done that I can see why you answered my query
the way you did.  Please allow me to summarize as I still do not have an
answer.  I confusingly wrote, "...when I run a program ddd knows the
locations of  objects and source.  I know about the preferences settings
and setting the working directory.  My program open a series of files
that are located in different places on my system." 

That was about as clear as mud.  Sorry.  I am not having any problem
with locating or using the objects or source code files, but I can see
why you thought that.  Nor am I confusing preference settings with
setting the workind directory.   I am having a problem with my program
finding and opening data files.  These files are a mix of ascii,
proprietary format, and an esoteric data format common to large, scale,
high resolution imagery.  I am constructing path names based partly on
command line parameters and values stored in textual configuration
files.  The files are located in a variety of places on our system, but
I am starting ddd in the main development directory.  The resulting
constructed pathnames are fully qualified from root.

What I find is, even if I have started ddd in this main directory and
have set the working directory (which I always do), my program cannot
find and open the configuration files that are in the working directory
to make the pathnames so it can locate the ancillary files which are
also in the same working directory.  So I hard code the pathnames and
then it can't find the ancillary files with those hardcoded pathnames.
But if I put the ancillary, configuration, and data files in my home
directory (please note this is not my working directory), I put them in
my home directory, and set the paths appropriately, they are found.
