:OK....  I wrote this little program to sort a set of names and corresponding
:numbers.  It compiles fine... but when I run it it crashes.  It usually
:crashes in the middle of the data inpput part.  It tells me "Exiting due to
:signal SIGSEGV       General Protection Fault at eip=000058dc ........".

You have a typical newbie error:


:void main ()    /* djgpp will change this to int for you, but don't make it
                             do so.  declare main legally in the first place.
*/

: int num;
: getnum (num);

: string datast[num-1];    // These two arrays have indices of
: int data[num-1];            //  0..num-2 (num-1 elements)
    // replace these with
string datast[num];        // Now they have indices of
int data[num];                // 0..num-1 (num elements)
