To conclude this thread, this solution works, provided I use edm
1-12-33 or greater.  I'm using edm 1-12-38 with epics R3.14.8.2.
I found that caget -t appends a blank character to the result. So,
to use the result in the name of the embedded window file, I had to
strip that off with sed. Without doing this, the name was constructed as
"pdu_trig_PP0 .edl" which did not exist.
Here is how it looks:

echo \'`caget -t TRIG:LI20:201:MODE`\'

'PP0 '

echo \'`caget -t TRIG:LI20:201:MODE | sed 's/[ \t]*$//'`\'

'PP0'
In the .edl file that launches the related display, I set the macro
MODE=`caget -t TRIG:LI20:201:MODE | sed 's/[ \t]*$//'`

and it works.

Hi Dayle,
You may do the following when you specify the macro symbol values as
name=SomeName,mode=`caget -t ModePv`
This opens the related display and sets name to SomeName and mode to the
value of ModePv.
