[SOLVED] Support for setting empty-string macros

Empty strings cannot be assigned to macros by the Set Macro operator or by the macros list parameter of the Execute Process operator.

The Set Macro operator's shortcoming is not a big problem since we can easily work around using "" in Generate Macro.
However, it is a bit troublesome that the Execute Process operator cannot define empty macros.
(There are workarounds of course but they are not nice.)

    Set Macro can create empty values in the latest version. Empty macros for other operators are on our todo list.

    Best, Marius
