Editing WoW:MACRO cast (section)

=== Optionset ===
You may use 'no' in front of any of these to invert the logic result. All of the options below except 'target' are actually conditions that the script will check before casting the spell. If any of the conditions in a set are false, the script will move on to the next option set, or the next semicolon (;) if there are no more; if all of the conditions in a set are true, the script will ignore any more option sets and cast 'spellname'. Once it successfully casts a 'spellname', the rest of that line is ignored (see Examples at bottom).

Because 'target=' is a command (not a condition), you can use multiple option sets to automatically cast the spell on the appropriate target (see Examples at bottom). Its important to note that '@mytarget' is an alternate form of 'target=mytarget' where you can use @Fred to cast on Fred, or @player to cast spell on self.
