ผมอยากทราบว่า โค๊ตต่อไปนี้ เขียนขึ้นโดยใช้ภาษาอะไรครับ

 // Hold Check
func SCR_AI_LIB_UNHOLD(selfAi, prevTS)
{
	if(prevTS == 'TS_HOLD' || prevTS == 'TS_HOLD_BATTLE'){
		UnHold(selfAi);
	}
}
// User Target Check
func SCR_AI_LIB_USERTARGET(selfAi)
{
	var userTarget = GetUserTarget(selfAi);
	if(userTarget != nil){
		SetAiTarget(selfAi, userTarget);
		SetTarget(selfAi, 'NOMINATE', userTarget);
		ClearUserTarget(selfAi);
		ChangeTacticsAi(selfAi, 'TS_BATTLE_NOMINATE');
		return 'ChangeTS';
	}
}

// User Skill Check
func SCR_AI_LIB_USERSKILL(selfAi)
{
	if(IsSkillUsing(selfAi) == 'YES'){
		ChangeTacticsAi(selfAi, 'TS_USER_SKILL');
		return 'ChangeTS';
	}
}

// Healing Check
func SCR_AI_LIB_HEALING(self, selfAi)
{
	var job = GetJobName(selfAi);
	var jobskill = GetJobSkill(selfAi);
	if( jobskill != 1021 && jobskill != 1003 && jobskill != 1042 )
	{
		return 'ChangeTS_Prev';
	}

	var option = GetOption(self);
	var needHealFriend = GetNeedHealFriend(selfAi, option.KeepRange, option.Heal);

	if( needHealFriend != nil ){
		InstantHold(selfAi);

		var SkillID;
		
		if (job == 'Valleria' || job == 'Elisa'){
			SkillID = 1021;
		} else if ( job == 'ElisaOfficer' ){
		  SkillID = 1042;
		} else {
			SkillID = 1003;
		}

		UseSkill(selfAi, needHealFriend, SkillID);
		ChangeTacticsAi(selfAi, 'TS_USER_SKILL');
		return 'ChangeTS';
	}
}
