- Yes, that is true for _current_ versions of MiNT. I was thinking of
- _future_ versions which will support virtual memory. For example:
-
- Process A does a Pfork(), creating process B. The datasegments of both
- processes are now located at the same virtual (not physical) adresses.
- Process A sends a VA_START message to B, passing a pointer to a string.
- Process B will not be able to access that string.

- You develop your own help-viewer. Your implementation would off course
- be freeware with sources available :-). There is a difference between
- making the ST-guide application a standard and making the ST-guide
- hypertext format a standard. The former doesn't make any sense, the
- latter does.

- I don't think there is a free (including sources) online helpsystem
- available? Assuming that you have no principal objections against _some_
- online helpsystem being part of the GUI standard, there's two choices:
-
- 1. A hypertext format that is completely new to the Atari platform.
- Even if that format is already in use on other platforms someone
- would still have to produce a viewer for the Atari platform, and
- hopefully make it available to others.
-
- 2. A hypertext format that is already supported on the Atari platform.
- ST-guide's format has some clear advantages over the 1st-guide and
- the Pure C/Pure Pascal formats. No-one would stop you from writing
- your own viewer and distributing it under your terms.
-
- Hmm, having said that I must admit that in case (2) you would also have
- to rewrite the hypertext compiler. I still think it is preferrable to
- choose a format that is already widely supported, but I'm open to any
- reasonable alternatives.
