> Is there something for VMS that works like SET PROMPT $P$G in DOS?

This question is becoming a FAQ !  (third time the last 3 months)

You have several options:

1)  Realize that VMS is not DOS and drop the idea of prompt displaying
    directory.

    I will recommend that solution !

2)  Get a CD.COM that changes directory and updates the prompt.
    Dozens of them are available and you can easily write your own.
    Then define a symbol to activate that COM-file.

    It only works if you use that symbol/COM-file to change directory with.

3)  Get and install one of the kernel hacks, that that intercepts calls to
    SYS$SETDDIR (which actually changes the directory) and also update the
    prompt (that info is also stored in P1 space).  

    This needs privs (and many system-managers do not like that), but will
    catch everything.

    I will recomend you to look for Brian Schenkenberg's version
    (sorry I can not produce a URL).

4)  Fix the SET DEFAULT command to run a program, which changes directory
    and sets the prompt appropriatetly.

    It does not need  privs and will work for all SET DEFAULT's both
    interactive and embedded in various COM-files. It does not work for
    programs calling SYS$SETDDIR.

    I have written such a utility and it is available at
    ftp://ftp.hhs.dk/setpmt/setpmt.zip !
