I just compiled the examples from Doug Young's Xt book on my DecStation
3100.  Of the ones I have tried, most seem to work.  I am having trouble,
however, with the one that uses command-line specified resources.  It is
ch3/rmtest2.c.  Here is the relevant part of the code:

#include <X11/Intrinsic.h>
#include <X11/StringDefs.h>

typedef struct {
   Pixel    fg, bg;
   int      delay;
   Boolean  verbose;
} ApplicationData, *ApplicationDataPtr;

static XtResource resources[] = {
  { "delay", "Delay", XtRInt, sizeof (int),
    XtOffset(ApplicationDataPtr, delay), XtRString, "2"      },
  { "verbose", "Verbose", XtRBoolean, sizeof (Boolean),
    XtOffset(ApplicationDataPtr, verbose), XtRString, "False"},
  };

XrmOptionDescRec options[] = {
  {"-verbose", "*verbose", XrmoptionNoArg, "True"},
  {"-delay", "*delay", XrmoptionStickyArg,  NULL}
};

main(argc, argv)
    int    argc;
    char  *argv[];
  {
    Widget          toplevel;
    ApplicationData data;

    toplevel = XtInitialize(argv[0], "Rmtest", options,
                            XtNumber(options), &argc, argv);
    /* Retrieve the application resources. */
    XtGetApplicationResources(toplevel, &data, resources,
                              XtNumber(resources), NULL, 0);
    /* Print the results. */
    printf("fg = %d, bg = %d, delay = %d, verbose = %d\n",
            data.fg, data.bg, data.delay, data.verbose);
}

This complies and loads fine, but when I try to run it and use the
"-delay" option, I get errors from Xt.  I have tried every way I can
think of (using -delay rather than -xrm "delay: 5").

Here is what happens:

% rmtest2 -delay5
X Toolkit Warning: Cannot convert string "-delay5" to type Integer
fg = 0, bg = 2, delay = 2, verbose = 0
% rmtest2 -delay 5
X Toolkit Warning: Cannot convert string "-delay" to type Integer
fg = 0, bg = 2, delay = 2, verbose = 0
% rmtest2 -xrm "*delay: 5"
fg = 0, bg = 2, delay = 5, verbose = 0


The last one works OK, but I want to know why the first one doesn't.  Isn't
that the way it should look with a XrmoptionStickyArg?
