Beav - Binary Editor And Viewer (I haven't tried it on Solaris 8 but
I expect it would work).
EMACS hexl mode.

   Emacs has a mode to do it.  If you're a VI person, the VIM editor
   (VI iMproved) has a nifty tool called xxd to make that easy.
   Example below.

   http://www.vim.org/


<Example>
me% cat hello.c
#include <stdio.h>
#define MD_EXEC_BIN "/usr/ccs/bin"
main ()
{
    printf ("hello, world\n");
    printf ("bin directory is %s\n", MD_EXEC_BIN);
    exit (0);
}

me% cc -o hello hello.c
me% ./hello
hello, world
bin directory is /usr/ccs/bin

me% xxd hello > hello.hex
me% cat hello.hex

me% echo bybye | xxd
0000000: 6279 6279 650a    bybye.

   Edit hello.hex and replace the "6865 6c6c 6f" (hello) with
   "6279 6279 65".

me% xxd -r hello.hex > hello2
me% chmod 755 hello2
me% ./hello2
bybye, world
bin directory is /usr/ccs/bin
