Try this little programming trick...
Note: The format string uses one args[], floats use 2 args[], ints use 1 args[]
      and so forth and so on.
If you need more parameter capabilities than this offers, just add more args[].

 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

/********************************************************/
/* Pseudo vsprintf ----- Limited parameter capabilities */
/********************************************************/

/*VARARGS1 PRINTFLIKE1*/
int Vsprintf (str, argv)

    char *str;
    char *argv;

{ /* Begin Vsprintf **********************************************************/

    /********** Local Declaration Section **********/

    char **args;
    int nchars;

    /********** Code Section **********/

    args = (char **) &argv;
    nchars = sprintf(str,
		     args[ 0],args[ 1],args[ 2],args[ 3],args[ 4],
		     args[ 5],args[ 6],args[ 7],args[ 8],args[ 9],
		     args[10],args[11],args[12],args[13],args[14],
		     args[15],args[16],args[17],args[18],args[19]);
#ifdef BSD4
    /* Berkeley's sprintf does not return string length: */
    nchars = strlen(str);
#endif

    return(nchars);

} /* End Vsprintf ************************************************************/

 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
