- Changes:
- {Date_time}: field DT of the structure
{date_time} is replaced with the private fielddt
. To provide maximal possible compatibilty
functions DT and Date_time. The first of them allows
to avoid changing code converting a structure
{date_time} to a REAL number (representing number of
milliseconds from either 1,Jan,1601 or from the
1,Jan,1BC depending on a platform); This
change allows using {date_time} on platforms not
having real numbers big enough to store amount of
milliseconds from the start of the era;
{File_path}still usesREALvalues to
store file times, but it is mostly
platform-dependent, and later this can be changed,
too;
- {Stream} + {File_stream} + {Memory_stream}:
To position in streams and to work with streams
size, structure{Long_int}.{long}used now (in
place of REAL). Thus, some small corrections could
be needed in existing projects;
- {DB}: in any case it is allowed to use table
aliases including single table in a query; this
allows to use nested queries both in case when a
nested or master query uses a single table in a
query;
- {DB}: Support added of operations
EXISTS(SELECT...) andNOT EXISTS(SELECT...)
as SQL operands;
- Method CONSTRUCT of a class can be recursive and so
it can have the modifier RECURSIVE;
- Another kind of an assignment statement introduced:
dstruc, BUT[(f1, f2, ...)]=sstruc[, BUT (fN+1,
fN+2, ...)]
It allows to assign fields of the source
structure variable (sstruc) to fields of the
destination structure variable (dstruc), where types
of those structures could be different. While
assigning, fields listed in BUT lists are not
assigned (skipped). For all other destination fields
it is necessary to exist correspondent source fields
(matching by the short name). And types of
correspondent fields must be equal. The assignment
is not working (not implemented) for array fields.
- While declaring a STRUCTURE type it is allowed to
use inclusion from another structure with the
statement:
LIKE {structure_type}
or
LIKE {Class_name}.{structure_type}
In result, all the fields of the source structure
type specified are added on the top level of the
declaring structure; In case of a source structure
from the same class, it should be already declared
above;
- Block comments in form -------------- 'text'
in calls to constructors of structures or objects
like
x={type}(field=value,
----------------- 'comment'
fieldN+1=valueN+1, ...)
- Fixes:
- Delphi/KOL, {DB}: reading Date fields from
databases;
- Fixes in compiling overloaded functions;
