I was about to ask how do I deallocate this... my impression is if have
to create a looping structure... correct?

re, memory leak... this code only gets called once (at start up) so the impact

of any leak is minor.

Taft,

actually that wasnt the exercise... although it is probably the way I
misstated
my original request that caused the confussion.... I dont really need the
alloc-
ation to be done on heap... but rather that the allocateion of memory to be
"sized" at run time rather than at compile time.  at run time i get the
numhosts
and numnodes and size the array at that time....  now that may dictate
that the memory be allocated on the heap rather than otherwise... I dont
know... i sure dont understand the details of ada...  But the only reason
we are using pointers and "new" is because I couldnt convins ada's to
handle my requirmens for a "unconstraned" data struture....

anyway, your sollution is fine for my app...  and I have not seen a better
one suggested..

thanks again....
