124.0. "Login questions make Fileview barf" by MASTIC::FARRELL (Money, there is no substitute!) Fri Feb 03 1989 16:05

    
    I had a topic in the old conference which refered to FileView.
    
    My problem was that I wanted to enter DECwindows in an account
    who's login.com file contain questions to the user.
    
    This bombs out of fileview.  
    
    I want the login file to check to see if it is the FileView window,
    and if so, don't ask the questions.
    
    Since FileView is run Interativly, checking ''f$mode()' doesn't work.
    
    Another thing I tried was :
    
    $ term = f$getdvi("sys$output","trm")
    $ if term .nes. TRUE then $set term sys$output:/inq
    
    This doesn't appear to work either.
    
    Can someone help?
    
    		Thanks,

F$getdvi("sys$output","trm") for the FileView process does return FALSE.
since sys$output is NLA0: for the FileView process.
 
So, the idea is good, but there seem to be a few problems in the deed:

Why ask if it is a terminal, get back the answer FALSE, and *then* do
a set term/inq on something which you know is not a terminal?  Did
your logic get reversed?

Why are you doing "$set term sys$output:/inq" instead of simply
"$set term/inq"?  Not that this matters.

And where is this value "TRUE" getting defined?  When I tried your
example, I got %DCL-W-UNDSYM for TRUE.

Try this instead:

    $ term = f$getdvi("sys$output","trm")
    $ if .not. term then $goto not_a_terminal
    $ set term/inquire
    $ ... other terminal-specific stuff
    $not_a_terminal:
    $ ...

You could also check that sys$input is type file.  For FileView,
sys$input will be sys$manager:decw$startvue.com, though this may
change in a future release.
