    compiler flags (used to be defined in Scanner and Parser) have been extracted for easier

    individual-method customization (using ST as scripting).

    The class side provides correspondingly-named variables, which hold the default values.

    howTo_fileInVSE:

        ParserFlags allowSTVExtensions:true.

        ParserFlags allowSTVPrimitives:true.

        ParserFlags allowSTXEOLComments:false.

    for stx debugging:

        STCKeepCIntermediate := true
