  done 
      
while read line
  do    for ((i=1; i < $2; i++))
          do    printf '%s ' "${line:${a[$i]}:${b[$i]}}"
          done
        printf '%s\n' "${line:${a[$2]}:${b[$2]}}"
  done <$1

@Don Cragun: there seems to be missing the $ sign preceding the i loop variable?
In the standards, a variable name (but, obviously, not a positional parameter) in expression in:
Code:
$((expression))

can be presented with or without a leading <dollar-sign> character to get the value to which the variable expands. At least in bash and in ksh, the same is true in the expression in
Code:
${array_name[expression]}
