Try this sort of thing:

#include <stdio.h>	/* for NULL and printf */

char *ProgName();

main( argc, argv )
char **argv;
{
	ProgName( argv[0] );

	/*
	** Code of your choice entered here
	*/

	Funky1();
}

Funky1()
{
	printf("My name is '%s'\n",ProgName(NULL));
}

/*
** ProgName - if passed a name will save a (private) handle to the name passed.
** Regardless, it will return a pointer to the current name stored.
*/
char *ProgName( pname )
char *pname;
{
	static char *myname = NULL;

	if ( pname )
		myname = pname;
	return myname;
}
