In VARIABLES.CSV, RETAIN variable were only flagged as such for GLOBALS, now local POU variable shoud be as well.
(* Test whether the keyword XXXX may be used as an identifier for:
* STEP, ACTION and TRANSITION name/identifier

* The XXXX names in the following code are merely a placeholder.
* They will be replaced by several identifiers before actual testing

*)
(* The identifiers that will replace the XXXX
* must be placed on a line starting with #
* All identifiers preceded by # are ignored!
* The identifier list must be placed inside an IEC 61131-3 comment.
