  DESCRIPTION
  -----------

    DO NOT USE THIS VARIABLE

    @_PTM, though being a publicly accessible variable, should NEVER be modified
    at run-time. @_PTM stores the Perl version of your non-Perl script code. As
    your PTM script is parsed, non-Perl sections are stored in the @_PTM array,
    using $_PTM_POS as an position marker, and calls to print from it are made
    in the return value of the _PTM() function -- a Perl script to be evaluated.
    It serves as temporary storage for non-Perl script behind the scenes while
    the PTM tags are parsed out and is then reinserted, via Perl "print"
    statements, when everything is ready to be displayed.
