Help with reading and assigning variables

Hi Gurus,

I have a file named log with 2 lines
Each line is a file name. eg

Code:
$ cat log
monday
tuesday


I need to read log and assign each output(filename) to a different variable.
The following doesn't work:-

Code:
while read A B
do
echo " a is ${A} "
echo " b is ${B} "
done < log


Here's the output:-

Code:
a is monday
b is
a is tuesday
b is

What I want is to have the following :-

Code:
a is monday
b is tuesday

Any ideas?? I'm using ksh.

Thank you in advance.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list. Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)). FILES
