   The following program is akin to the MUF primitive EXPLODE, if any of
you are familiar with MUCK.  Anyway, it works like this:
   x = explode(char *data, char *trigger, char **array);
  Where x is an int, *data is a a data string, *trigger is the string to
explode on, and **array is filled by results.
  So,  x = explode("Hello.Test", ".", results);
 That SHOULD put "Hello" in results[0] and "Test" in results[1].  But,
for some reason, I keep getting a bus error.  Program follows:

int explode();
main()
{
	int c,cc;
	char **arr, x[50], trig[5];

	gets(x); gets(trig);
	cc = explode(x, trig, arr);
	for (c=0;c<cc;++c)
		printf("%s\n", arr[c]);
}
int explode(char *data, char *trigger, char **array)
{
	int x;
	int last=0, ctr=0;
	char dummy[512];

	for (x=0;x<strlen(data);++x)	{
		if (!strncmp(&data[x], trigger, strlen(trigger)))	{
/* Here's the bus error*/  strncpy(array[ctr], &data[last], x);
			last = x+strlen(trigger);
			++ ctr;
		}
	}
	return ctr;
}

  Please post suggestions, etc., to sah@gnu.ai.mit.edu.  Thanks.
