This function joins a list of strings separated with a separator into one string and retains the empty strings.
Parameter: separator
For example:
If the
CopyField functions return the values 7, 7, <nothing>, 10, the
result is 7;7;;10.
<nothing> in this example
means that the HOLE_6 value field is not output because its row is
stepped over based on the row rule.
