Changing tags from v1 to v2

hi there

im a newbie to tagging mp3

my question is

I want to know how i can change tags from version 1 to v2 and just save them as v2 tags

I have to tag all my music albums to use in a piece of software called the pc jukebox

only trouble is when I combine artist name and track name together I need only do this for compilations albums

beacuse tag v1 only supports file name upto 30 characters

any help please

regards

johnboy

thanks for everybodys help but ive sorted it now
