I liked Sean's earlier suggestion in the 'Env variable from C-shell
scripts':
"To figure out if a particular DM is a Display Manager or Foxview, you
could check the display manager environment variable ENV. Perhaps you
were thinking that when you asked your question.
pref -DMNAME ENV
If it returns /usr/fox/wp/sys/Change_Env/{something} then it is a
display manager.
Or if it returns somethings that ends in .env ( grep '\.env$' ) then it
is likely to be a foxview.
This does make the assumption that all your display manager environments
are in the default place. Or that only your foxview environments end in
a .env"

Hi Andreas,
You could check for a variable that exists in Foxview but not in Display
Manager, like FVWHAT. In a simple shell script driven from a button on
a graphic you can check to see if the variable is not null. If it is not
null then it will be foxview. If it is null then it will be a display
manager. I can not remember when the FVWHAT came in to existence, but
it is there in Foxview 9.02
Sean
#!/bin/sh
# $1 is the Display Name i.e. $DMNAME
type=3D3D`/usr/local/pref -$1 FVWHAT`
if [ "$type" ]
then
echo "FV"
else
echo "DM"
fi

Hi,
how is it possible to check which HMI (FV or DM) an Operator has been
used to start a script by clicking on a button?
All what the script knows is:
- DMNAME
- HOST
The output should be: "FV" | "DM"
An AW could provide both applications at the same time.
Regards,
Andreas
