Add, 4D Write expressions did not require a value to be returned, so it was acceptable to have embedded Query, Create Set, Intersection, Union, Use Set, Selection to Array, etc…, commands in the 4D Write document.
Converted to WritePro, the same expressions return “Undefined”. It is a change in behavior that requires editing 1000’s of documents. And WritePro does not provide an easy way to replace those expressions with a method call that will not return “Undefined”.

For example: 100+90 Current date projectMethodThatReturnAValue For QUERY command, the execution will produce a selection of record in memory. It does not return a value that can be inserted to the document.

It would be easier is the command SET ALLOWED METHODS did this for us automatically. Thanks for your help John!
