All,

Everyone appears to agree: great product, but poor documentation remains
it's Achilles heel, even for experienced users. I more or less quit the
product largely because it took so much time trying things out or
understanding the precise meaning (this is even more the case when one uses
BlackBox incidentely).
So yes, a good learning manual (even now) would be great.

Practically though it's extremely doubtful anyone within the users group is
going to write anything on the scale of Reisner or otherwise. So how about a
much smaller scale approach. Let's pick a small number of subjects where the
documentation really is poor and where the extra help (particularly prof
Warford's chapters on the simple basics of forms programming and Douglas'
effectively 2 guides (short general guide and a short database programming
guide) leaves off.
A few examples:
1. ASCII programming (my favourite first confusion: as a newcomer being used
to just reading and writing to files I did not understand for quite a while
the BlackBox example first making a view of it etc.),
2. Embedded views (the examples of embedding a view in a text model so it
floats along was another beginners' wonder: nice gimmick but not exactly
practical).
And so on. I could make a long list of big and small items which I found
obsure, misleading, confusing along the way and what I still do not
understand.

If this strikes a chord the I suggest the following. Let everyone send in a
list of upto 10 items which they found rather confusing and difficult when
they learned BlackBox (with such explaination as deemed necessary) and a
number of items which they do not understand now or find very poorly
written. Collating these responses will quickly show up those items where
some additional documentation would be most useful. With some united effort
we could then start to address these piecemeal (devide and rule).

Regards,

Bart

Subject: Documentation and pointers


Hello,

I am in the midst of reading the TextModels documentation since I wish
to understand how Coco/R uses it to produce output. As I read along I
find many references to concepts which are not defined within the
document but seem to hint that the concepts are defined elsewhere. The
author of the document obviously had a full understanding and knowledge
of all the parts of the Blackbox framework and hence either forgot or
purposefully did not define those concepts within the TextModels
documentation (for example "text setter").

Knowing of the "purposefully left unsaid" emphasis by Dr. Wirth I assume
that the Blackbox documentation is following this principle. I have a
few comments.

For program construction one wants to follow the principle of "one place
only" so that a change in only one place is propogated throughout the
whole program. This makes maintanence easier.

For human understanding and learning one wants many references to the
same concept in slightly differing forms. This helps disambiguate the
concept (which resides in a large multidimensional space). One wants to
point to the concept by "triangulation". This makes document maintanence
difficult since changes in a concept can not be easily propogated
throught the documentation.

The use of "one place only" and "multiple descriptions" are at variance
with each other and yet to have someone use what you have created it is
necessary to "teach" what you have done, to cast the creation in as
clear and as bright a light as possible, otherwise all of your efforts
may be lost to the casual reader who, just might be a large investor!

Thoughts on solutions
o Automation: create some bit of sotware that tracts all forward
pointers (document links) and creates hidden backpointers that can be
used to alert the document writer when changes are made. This allows
the writer to reexamine those forward pointers to determine if those
sections need to have their text changed also.

o User oriented statistics: Allow some subset of users to insert
question marks into documentation "[?]" that is then returned to the
document writers for clarification and embellishment.

o Time: Good documentation writing takes time ...

In general for the Blackbox documentation it is not possible to step
into the middle of it and extract what one needs. One must absorb the
whole in order to use a part. This is not an optimal use of one's time.

There must be some way that the Blackbox user community can help Ominc
improve its documentation.

-Doug
