Here it is again:

code in file1.c:

char *a_string_array[] = {
  "Now is the time for all good men",
  "To destroy the earth",
  "And have beer parties across the galaxy.",
  ""
};


code in file2.c:

#include <stdio.h>



extern char **a_string_array;



int main(void)
{
  int i=0;
  char *a_string;
  

  a_string = a_string_array[i];
  while (a_string[0])
    {
      printf("%s\n", a_string);
      i++;
      a_string = a_string_array[i];
    }
  
  return 0;
}

Good thing I save my messages. Now in most C books,
they say `char **string_array' is equivalent to 
`char *string_array[]'. Now why does it crash?

Yes, it is ;-). What was I thinking? But during the 
time I wrote my sig, I thought of nothing else. (Have 
any good ones?)

There was a thread discussing this a few days back. But
I never pay much attention to these things. But if I
know those MS guys, the VFAT entries for LFN must be
stored somewhere on the disk. Methinks a TSR can do
this. It should be possible to read and write these 
entries in DOS mode using a TSR program. It loads into 
memory when Windows shuts down to DOS mode and
replaces that part of Windows that does the LFN thing 
in GUI mode. But then again, why do all that 
unecessary work? That's why I still use Windows when I 
program using DJGPP.
