I have seen braces used around a section of code. What would be the pros/cons for doing this?

{
   # ----  START POSE  ----
    if ($pose_name eq ''){
    print "ERROR: \"start\" POSE - NOT FOUND"
    }

    for ($i=0; $i<$armload_cnt; $i++){
    if ($armload_mass[$i] == 0){
    print "ERROR: ARMLOAD $armload_num[$i] - MASS VALUE IS ZERO"
    }
    }
}
