I need to create dynamic filenames based on the input parameter for a selection set in a variable.
How can I create a filename for output (or as a part of file operation, like copy, rename) where a part of the filename uses the content of a workflow variable?

There is a lot about extracting a filename from inpout, but I want to define the filename dynamically, e.g. JANUARY.csv, FEBRUARY.csv ... depending on selection.

In script

begin
SetVariable('<file_name>','august');
result:=true;
end;

than in file name

c:\temp\<file_name>.txt
