[Info-vax] defining a symbol as an action invoked when entered as command

[Phillip Helbig undress to reply]

I can do something like this in a command procedure:

   $ DEFINE/GROUP/NOLOG HERE 'F$ENVIRONMENT("DEFAULT")'
   $ EXIT

and define a symbol to run this procedure.  Works fine.

Is there anyway to get the same result as a symbol which gets evaluated 
only when entered as a command?
