Try:

Code:

while read A && read B
do 
  printf "This is \$A: %s\n" "$A"
  printf "This is \$B: %s\n" "$B"
done < file

But maybe you mean this:

Code:

while read _ A _ && read _ B _
do 
  printf "This is the second value on the line, \$A: %s\n" "$A"
  printf "This is the second value on the line, \$B: %s\n" "$B"
done < file

The underscore is used to capture and discard the first field and a potential last field after the second field (if ever there should be one)
