I wanted to thank everyone for their help.  There were a few questions
about some specific code I wrote, namely:

>   begin
>      B := vechandle(NewHandle(k * sizeof(integer)));
>      C := vechandle(NewHandle(k * sizeof(integer)));
>      [...]
>      (* code to free space for B and C goes here *)
>   end;

I did not want to allocate space for the whole array, which was 10000
locations, because that would have run my machine out of memory.
(This block is in a recursive call.)  Instead, I only wished to
allocate space for as much as I needed for an array of that type.
Thus, the "k". 

Since I am a C programmer, I am used to dealing with pointers and
allocating as much space as I need, rather than allocating all the
space that is declared for a variable of that type.  This is probably
not such a good way to do things, as the Pascal compiler may not allow
you to allocate space in that manner.  (I don't know -- this is one of
my problems, dealing with a nonstandard compiler in a language and
programming environment I am not comfortable with.)

Thanks for all your help, anyway.
