The following is a little more compact than Marty Sasaki's posting a
couple of weeks ago.  Note the recursive call inside:

$ ! Delete directory tree  JA Lloyd 83 12 16
$    if "" .nes. P1 then goto doit
$    inquire P1 "What disk and subdirectory ?"
$doit:
$    if "" .eqs. P2 then P2 = 0
$    P2=1+P2
$    disk=f$parse(P1,"","","DEVICE")
$    base=f$parse(P1,"","","DIRECTORY")
$
$ subloop:
$    on warning then exit 1
$    context = f$search(disk+base+"*.DIR",P2) 
$    if "" .eqs. context then goto delete_some
$    subname   = f$parse(context,"","","NAME")
$    subcontext= disk + base - "]" + "." + subname + "]"
$    @DISK$USER:[JAL]deltree 'subcontext 'P2
$ goto subloop
$
$ delete_some:
$    write sys$output "will DELETE ",disk,base,"*.*;*"
$    DELETE 'DISK''BASE*.*;*
$    exit 1
