If the procedure you developed for the trigger, when PUTed, included a
placeholder after the Return, then I would expect you should have a value
after the RETURN.
The PUT command is quite happy to accept a procedure that has no arguments
or Return values specified.

It's not so much that triggers return values, but stored procedures can. In
the help files, read "using stored procedures."
For example, you can call a stored procedure to set a variable to the value
after the last "RETURN value" statement.
Dennis, you were still the developer of R:Style back in 6.5 when "RETURN
value" became a valid syntax. I can't remember what change you had to make
to R:Style then, but you had to do something to distinguish it from the
RETURN at the end of a command file.

Albert,
I am curious where you found this tidbit of info in the documentation.
I was under the impression that Triggers were not supposed to RETURN
values
since They are automatically called and have no way for the user to
interact
with them after they complete execution.

Hi, all. The system expects the trigger to return a value to a calling
procedure. Zero is as good as anything.
