How to program an indicator to give a sound alert or send email

[[Deleted]]

I have an indicator (ASC Trend, im sure you all have heard of it) which is said to give a sound alarm when the arrows are shown, but it doesnt seem to give any sound. When i checked the codes, it doesnt attach any sound file, nor does it send me any emails, which is most probably because there are no sound files attached to the indi or my email isnt even written in the code. So can any of you programmers enlighten me on how i can edit my indi to send email and give a sound alert? Or can any of you help edit my indicator to really give a sound and send email? i base my trading on this wonderful system, so please help me!

The following are the source codes to my ASC Trend indi. I will use this knowledge to apply alerts for other systems. Hey, teach a man to fish, and he can eat for a lifetime.
