David,
eval is a project method that will execute a PROCESS 4D TAGS. I am pretty sure
Erick provided an explanation to what that method does.

We have great support from 4D! (Erick)
This is an effective 4D tech support work-around to the problem of “Undefined”.
Here “WParea” is a 4D Write Pro object.
After running this method on our converted 4D Write to 4D Write Pro documents,
none of the embedded statements return

Thanks!!!
I’m about to evaluate a work-around from the faithful tech support team…

Hi David,
If you are insert an expression into a 4D Write Pro document, the expression
should return a value.
For example:
100+90
Current date
projectMethodThatReturnAValue
For QUERY command, the execution will produce

John,
We can manually limit the entry of commands and methods, since we control the
UI that inserts expressions. It would be easier is the command SET ALLOWED
METHODS did this for us automatically.
Thanks for your help John!

There is no such command SET ALLOWED COMMANDS, only SET ALLOWED METHODS which
only works on methods. If you allow users to enter "QUERY" then they can also
enter DELETE SELECTION. The documentation says:

I see two options:
1. Submit a bug/feature request to 4D and hope they change it to return nothing
instead

2. Replace all of your QUERY commands with a method that returns an empty
string.
I don't use 4D Write Pro, but I think automating the replacement in 4D Write
