I use em, becouse i think it makes the code look cleaner. Im used to C languages so brackets makes sense. Ofcourse with "IF's" i dont always use, if theres just one line to do. In some cases, there needs to be lots of "IF's" and set variable then return. If using brackets, it takes almost 2x lines to do it. Then i might use the number to let EUO know, how many lines to process.
Ill use brackets even with subs.
