All code and data is *defined* to reside in a resource. Even A5
|

|
|
relative data is defined to reside in a dummy resource of ResType
|
|
|
|
'gbld'. Code always resides in a resource. Because a code/data
|
|
|
|
is built of many modules, when walking through a resource we must
|
|
|
|
point back to the modules in the order they were defined. This is
|
|
|
|
done by requiring the entries in the Modules Entry table to be
|
|
|
|
ordered by resource/resource-number and by the location in that
|
|
|
|
resource. Hence, the resource table entry points to the first
|
|
|
|
module making up that resource. All modules table entries following
|
|
|
|
that first one with the same restype/resnum are contiguous and offset

from that first entry. */

Modules table entries are ordered by their appearance in a resource.
|
|
|
|
(Note that having a single module copied into two resources is not
|
|
|
|
possible). Modules map back to their resource via an index into the
|
|
|
|
resource table and an offset into the resource. Modules also point
|
|
|
|
to their source files, both the definition module and implemention
|
|
|
|
module. Because modules can be textually nested within other
|
|
|
|
modules, a link to the parent (containing) module is required. This
|
|
|
|
module can textually contain other modules. A link to the contiguous
|
|
|
|
list of child (contained) modules is required. Variables, statements,
|
|
|
|
and types defined in the module are pointed to by indexing the head of
|

the contiguous lists of contained variables, contained statements,

Contained Statements table. This table is similar to the Contained
|
|
|
|
Variables table except that instead of VARIABLE_DEFINITION entries, this
|
|
|
|
module contains STATEMENT_NUMBER_DEFINITION entries. A statement number
|
|
|
|
definition points back to the containing module (via an index into
|
|
|
|
the module entry table) and contains the file and resource deltas
|
|
|
|
to add to the previous values to get to this statement.
|
|
|
|
All entries are of the same size, making the fetching of data simple. The
|
|
|
|
entries in the table are in order of increasing statement number within the
|
|
|
|
source file.

The Contained Statements table is indexed from two places. An MTE contains
|
|
|
|
an index to the first statement number within the module. An FRTE contains
|
|
|
|
an index to the first statement in the table (Possibly. This is slow.) Or
|
|
|
|
a table of fast statement number to CSNTE entry mappings indexes into the
|
|
|

table. Choice not yet made. */
