concat string with contents of variable

[Len Burman]

I have some code in a form which inputs a friends email address and when you
submit it sends the message to the person at the address. I want to be able
to email to the variable name and also a hard coded address. When I actually
input two addresses, it sends to both. The partial code reads:
Set objMail = CreateObject("CDONTS.NewMail")
objMail.From= request.form("youremail") 'Specify sender's address
objMail.To=request.form("yourfriendemail")

yourfriendemail is a variable gotten from a form. I want to replace it with
the contents of yourfriendemail and ab*@comcast.net. When I input on the
form ab*@bill.com; ab*@comcast.net it sends to both. I have tried concat()
adn using a + sign to concatenate.
