My guess (although I am not by any means authoritative on this)
is that this is just saying that writing "read" without supplying
an argument is a bashism. In bash, "read" by itself reads a line
into a variable named REPLY, but the standard requires a variable
name to be supplied.
Perhaps the fix is as simple as changing
read
to
read REPLY.
You can read about bash's "read" command by typing "help read" at
a bash prompt. You can read the POSIX standard for the "read"
command at
