Analytica 4.0 beta Release Notes/4.0.0.37

Changes in 4.0.0.37

The notes here are for the next beta build that is expected to be released. For the current beta build, see Analytica 4.0 beta Release Notes/4.0.0.34.

(straight bug fixes and minor textual changes not listed)

Attrib of Obj: Returns Null if attribute value is not defined. (Formerly returned Undefined)
The defaultValue for non-specified cells to MdTable is now Null (formerly it was Undefined)
Fixed bug in which local index objects were not being reclaimed.
Introduced the MetaIndex..Do construct.
Several bug fixes impacting Meta-Inference.

External values from variables having an explicit domain (list, list-of-labels or index domain) can be shown in Symbol and Color roles (as categorical).
Pivot controls use Blank, rather than "No Index", when no option selected.
is hidden in browse mode.
For J:=X Do expr, now iterates over IndexValue(X), not over the value of X which occurred previously. These differ when X has a self-index. The new functionality means you can use A[X=J] from within the body expr.
For a:=X Do expr now allows X to be a general expression, not just an index as was previously required. When an array, a iterates over all elements of X. When X is an identifier, For a:=X Do ...' and For a[ ]:=X Do ... are the same unless X has a self-index, in which case For a:=X Do ... iterates over IndexValue(X), while For a[]:=X Do... iterates over the main value of X, computed in context.
In pivot controls and graphing role pulldowns, the option formerly labeled "No Index" or "No Dimension" now displays as a blank label. Select the blank option for "None".

It is possible to specify a default value, specific to a table, to be used as the default value when new rows are added to the table. The table-specific value can be an array, with a different default for each column. This must be set via typescript. See Table Splicing

You can control the global atomic default used as the default for table cells when new cells are added (and a table-specific default does not exist). Default now is 0.0. Can use blank -- new cells show up blank. See Table Splicing

A table definition accepts blank cells. For example: Table(Time)( 1, ,2) -- in this example, the second cell is blank. When this evaluates, a warning is issued, and if ignored, the blank cell evaluates to Null.

Legacy tables having no commas are now parsed, and re-written to have commas. For example: Table(Time)(1 2 3) is rewritten as Table(Time)(1,2,3), so that legacy models that omitted commas are accepted.

Bug fix to often seen problem in which non-functional scroll bars appear on tables when window is maximized.

In a pivot control, the option formerly labeled "No Index" is now displayed as a blank label.

The profiling library has been reworked to use VarTerms rather than string identifiers. This has the benefit that you can double click on the row header when looking at a report and hyperlink to the object named.

Access to hidden definitions via the ADE API has been restricted. There is now a new error code, CAEngine::ErrorCode == 70, indicating that the requested definition is hidden, which may be returned by CAObject::DefTable or CAObject::GetAttribute.
