if/endif use with defined variables

[Matt Alonso]

Hi Eduardo,

Forgive me if I'm addressing the wrong issue again but should your if
statement have "vmerid >= 5.0" instead of "vmerd >= 5.0"?

Also, for what it is worth, GRADSUSR at list.cineca.it is the old grad's user
list, you can find info about the new one here:
