Ack!  Now I see the 1211 in the C.  Thanks Barbara!!!

Voila!  I even got the right answer!  (after I changed the pin to ascii)

Thanks to all who helped!  I'm very grateful for these lists, and especially
for the generous pros who inhabit them.

Tom, this is a difference in debugging behaviour.  With the RPG
debugger, :x for a pointer means to show the contents of the pointer in
hex.  (:c for a pointer means to show its contents as character.)

With the C debugger, :x for a pointer means to show the pointer value in
hex.  To see the contents of the pointer, use *buf.

eval *buf:x 10

To save yourself some trouble, prototype your char * pointer as

D Sha1            PR                  ExtProc('sha1')
D  Buffer                         *   Value Options(*String)

Then get rid of your PIN# and p_PIN# temps and just do

   Sha1(PIN: 4 : pdiv : r_digest);
