Did you peruse your shell's man page? This works with recent shells:
Code:
while read line
  do    #echo $line
        gendage=${line:9:3} #Loc 9th character in the line and select the next 3 Char
        gendage=${gendage##* }
        [ "${gendage:0:1}" = "B" ] && gend="M" || gend="F"
        age=${gendage:1}   
        lastnam=${line:12:20} #loc 12th character in the line and select the next 20 char
        lastnam=${lastnam%% *} 
        firstnam=${line:32:21} #loc 32nd character in the line and select the next 21
        firstnam=${firstnam%% *}
        echo "$lastnam;$firstnam;;$gend;$age;;"
  done < file
