`write` does not define the filename if it has a `separator`-option

write does not define the filename if it has a separator-option. File should be named test.dat. See example here.

Without separator-option it works.

The problem seems to be that the last string in quotations is selected:

File is called TEST

Also if you set the header option the file is named after the header option value:
