$! SET VERIFY
$!
$! For example, if you unpacked perl into: [USER.PERL5_00n...] then you will 
$! want to cd into the tree and execute Configure:
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure 
$!
$! or
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure "-des"
$!
$! That's it. If you get into a bind trying to build perl on VMS then 
$! definitely read through the README.VMS file.
$! Beyond that send email to vmsperl@perl.org
