Forums mIRC Help Creating a NICK alias

I am new to IRC and wish to make a NICK alias. I want to be able to add things to the end of a default nick. I've tried a couple things:

/nn /nick {abc}Name-$1

and

/nn {
/set -n %default {abc}Name
/nick %default-$1
}

I think part of the problem is that I need to use curly braces in the name. I also need to add things to the end of the name, but putting a $1 after the name without a space seems to cause a problem... Can anyone help? Is there a way to 'escape' certain characters?

Thanks
