- keywords 'virtual' and 'uses' were added.

- '{}' and '(**)' comment types were separated.
- tokens now AnsiStrings
- the comments are now handled better, ptop now does multi line comments.
- added debug prints to verbose option
        'line in-<number> out-<number> symbol "<name>" = "<value>"'
  the <value> is truncated in the middle. this means visible beginning and
  the end.
