Walter,
As far as I can tell, the people at the ATM teleconference
voted to have double quotes around strings. There were no
unanswered questions about the intent of the author(s) about
this. The decision was made, and I would not resurrect any
BIRD-s on the string discussion. We simply didn't think that
some of the examples may need to be corrected according to
this definition of the string. So if we do any amendments,
we should correct the string examples to be in agreement with
the definitions BIRD.
Regarding Bob's comment, I wouldn't write it off so fast. I
agree that we should strive for consistency and simplicity.
I am not sure that I fully understand everything Bob wrote
yet, but I just looked at Table and List, and they are indeed
inconsistent. Why couldn't we treat List as a one row Table,
and use the same syntax for both?

Bob,
Thanks for making me look at how Table (and Labels) where defined in
IBIS
5.0)
| (Format Table
| (Labels Row_No Time_UI Density)
| (-50 -0.1 1e-35)
| (-49 -0.98 2e-35)
| ...
| (0 0 1e-2)
| ...
| (49 0.98 2e-35)
| (50 0.1 1e-35)
| ) | End Table
And it is clear to me that the values of Lables are strings that are not
surrounded by ".
This is clearly an example of the intentions of the developers of this
language in the original spec of how string tokens without impeded
blanks
should be treated in the parser - that " would be optional in this case.
Since we are not deprecating Table then we must support it and how
strings
are handled in general. So I will be resurrecting my Sring Quating BIRD
as
an amendment to Arpad's definitions BIRD.
As far as Bob's other comment, Bob continues to make something that is
quite
simple quite complicated. I think the use of Labels in the context of
Table
parameters is quite clear - and I think that Lables in the context of
List
parameters is quite clear.

Arpad:
We need to address the Labels rules for both List and Table at
the same time.
The rules look almost identical and yet there appear to be
some significant differences.
List:
One of the leaves of the of branch containing this List can be named
"Labels" and, if provided, is to be assigned a string value
containing a list of List entry names.
Table:
The parameter name "Table" names a branch of the parameter tree
rather than a single leaf.
One of the leaves of the of the parameter containing this branch
can be named "Labels" and, if provided, is to be assigned a string value
containing a list of column names.
-----------------
Several problems:
"Format Table" is a special name for a branch as shown in the
examples on pages 141, 146, 147?
Labels is always a special case leaf of a branch with a special
syntax (plus some possible number of argument rules):
(Label <string> <string> ... <string>)
"Format List" is permitted for Model_Specific parameters.
Since List is not listed as valid for any Reserved Parameter,
Labels for List would never appear in the Reserved_Parameters
block.
The Model_Specific format needs to be extended to allow a Labels
with just the string entries only when List is used. A leaf
syntax is not given in for Model_Specific cases.
(parameter_name (Usage <usage>) (Type <data_type>)
(Format <data format>) (Default <values>)
(Description <string>))
add?
(parameter_name (Usage <usage>) (Type <data_type>)
(Format <list format>) (Default <values>) (Labels <sring> ...)
(Description <string>))
We have not even mentioned tree or branch or leaf yet, and this
is critical to the rules (to be fixed by re-organization).
For consistency, Labels could follow the same rules for Table
and be a leaf of List. For example.
(Process (Usage In) (Type Integer) (Usage In)
(Format List (Labels "a" "b" "c") 1 2 3)
(Description "your description"))
or
(Process (Usage In) (Type Integer) (Usage In)
(Format List 1 2 3 (Labels "a" "b" "c")) | any order??
(Description "your description"))
or be in any other position within the list.
For Table, the corresponding example is:
(Multi-process (Usage In) (Type Integer) (Usage In)
(Format Table
(Labels "a" "b" "c") | It is not stated that Labels
| must be first
| Also the <string> arguments do not
| have quotes in Section 6c.
(1 2 3) (2 3 4) (3 4 5))
(Description "your description"))
---------------------
The whole point is that we are introducing an inconsistency.
We need to document all of this fully and clearly. This means
dealing with Table at the same time.
