Hi: I'm having a somewhat wierd problem. I have a program that
when compiled and executed behaves differently than when it is executed
under Saber. (I understand this may be a Saber problem, but I was
wondering if any of you have run into it and have a work around).

I have a program that does something like:
    top = XtAppInitialize(NULL, "Graph", 
			  optionList, XtNumber(optionList),
			  &argc, argv,
			  NULL, NULL, NULL);

    XtGetApplicationResources(top, NULL,
			      resources, XtNumber(resources),
			      NULL, 0); 
where optionList and resources have been initialized thusly:
static XtResource resources[] = {
    { "xlabel", "xlabel", XtRString, sizeof(char *),
	(unsigned int) &xlabel, XtRString, (caddr_t) "X Values" },
    { "ylabel", "ylabel", XtRString, sizeof(char *),
	(unsigned int) &ylabel, XtRString, (caddr_t) "Y Values" },
    { "title", "title", XtRString, sizeof(char *),
	(unsigned int) &title, XtRString, (caddr_t) "Contour Plot" },
    { "infile", "infile", XtRString, sizeof(char *),
	(unsigned int) &infile, XtRString, (caddr_t) NULL },
    { "wire", "wire", XtRBool, sizeof(Bool),
	(unsigned int) &wireframe, XtRString, (caddr_t) NULL },	
    { "surface", "surface", XtRBool, sizeof(Bool),
	(unsigned int) &surface, XtRString, (caddr_t) NULL },	
};

static XrmOptionDescRec optionList[] = {
    { "-xlabel", "*graph*xlabel", XrmoptionSepArg, "X Values" },
    { "-ylabel", "*graph*ylabel", XrmoptionSepArg, "Y Values" },
    { "-title", "*graph*title", XrmoptionSepArg, "Contour Plot" },
    { "-wire", "*wire", XrmoptionNoArg, (caddr_t) "True" },
    { "-surface", "*surface", XrmoptionNoArg, (caddr_t) "True" },
    { "-in", "*infile", XrmoptionSepArg, (caddr_t) NULL },
};

Now, the program compiles and executes fine. But I'd like to run this
under Saber. Unfortunately, when I try to do this, XtGetApplicationResources
doesn't seem to notice the passed in argc, argv when I do this.

How is this really supposed to work? It looks like XtAppInitialize
saves away the arguments and sets argc to 1, and then XtGetApplicationR..
gets the data from the saved area. Why does this work in my executable
but not under Saber? 

Thanks for any help you can provide in advance. (BTW, I've tried reinitializing the variables within Saber, re-running etc.. but nothing
seems to work).
