hello all,

im trying to debug a program using Labwindows/CVI (V5.5) IDE running in a dosbox (windows xp).

However as the program requires command line parameters i cant see a way to debug the program because CVI doesnt brake on breakpoints when running standalone executable, and when running the program in debug mode one cant fill the argv members, so i thought what about hardcoding the char arrays in global space then passing the arrays to the argv members, but after trying a few different ways i cant get past the compiler.

can it be done? im not an expert, been programming for a few months now.

i have been reading around this sight and have learned what argc - argv mean but dont know enough about 'c' to work out a way to do this.

my program (well most of it belongs to Ray Gardner - Public Domain) is here:
Code:
//#include <ansi_c.h>
#include "scaldate.h"

#if ISO_CAL			/* MONDAY == 0 */
	#define ADJ 5
#else 				/* SUNDAY == 0 */
	#define ADJ 6 
#endif

unsigned DOW(unsigned y, unsigned m, unsigned d)
{
	if (m < 3)
	{
		m += 13;
		y--;
	}
	else m++;
	return (d + 26 * m / 10 + y + y / 4 - y / 100 + y / 400 + ADJ) % 7;
}



#include <stdio.h>
#include <stdlib.h>
    
    


/* argc is the number of command line parameters including the name of the 
   program , argv[] is an array of pointers to the command line parameters */
int main(int argc, char *argv[])
{

	
	
	int ch;
	int Day;
	void usage(void);
	unsigned d, m, y, days[] = {31, 29, 31, 30, 31, 30,
								31, 31, 30, 31, 30, 31};
	
	char *day[2][7] = {{ "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"},
					   { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"}};
						 
	char *month[] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun",
					 "Jul", "Aug", "Sep", "Oct", "Nov", "Dec",};
	
					 
	if (4 > argc)
		usage();
	y = atoi(argv[1]);
	m = atoi(argv[2]);
	d = atoi(argv[3]);
	if (!m || m > 12)
		usage();
	if (!d || d > days[m - 1])
		usage();
	if (y < 100)
		y += 1900;
	Day = DOW(y, m, d);
	printf("DOW(ISO_CAL=%d) returned %d, so %d %s %d is a %s\n",
		ISO_CAL, Day, d, month[m - 1], y, day[ADJ - 5][Day]);
	
	printf ("Press [Enter] to continue");
   while ((ch = getchar()) != '\n' && ch != EOF);
   return(0);
	
		

}



void usage(void)
{
	int ch;
	puts("Usage: DOW yy[yy] mm dd");
    
    printf ("Press [Enter] to continue");
    while ((ch = getchar()) != '\n' && ch != EOF);
	
	exit(-1);
}
