   On any other system, this is what happens:

$ echo "Hello World." | { read; echo "$REPLY"; }
Hello World.

   And, since the OP is using ksh, the same result should obtain
   without the braces:

$ echo "Hello World." | read; echo "$REPLY"
Hello World.

   If this is not what happens, there is something wrong with either
   the OS or the shell.

   To dan.rickhoff: What happens if you use bash instead of ksh?
