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

resource. Hence, the resource table entry points to the first

(Note that having a single module copied into two resources is not

to their source files, both the definition module and implementation

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,

|
|
Contained Statements table. This table is similar to the Contained
|
| 328 |
|
|
Variables table except that instead of VARIABLE_DEFINITION entries, this
|
| 329 |
|
|
module contains STATEMENT_NUMBER_DEFINITION entries. A statement number
|
| 330 |
|
|
definition points back to the containing module (via an index into
|
| 331 |
|
|
the module entry table) and contains the file and resource deltas
|
| 332 |
|
|
to add to the previous values to get to this statement.
|
| 333 |
|
|
All entries are of the same size, making the fetching of data simple. The
|
| 334 |
|
|
entries in the table are in order of increasing statement number within the
|
| 335 |
|
|
source file.
|
| 336 |
|
|
|
| 337 |
|
|
The Contained Statements table is indexed from two places. An MTE contains
|
| 338 |
|
|
an index to the first statement number within the module. An FRTE contains
|
| 339 |
|
|
an index to the first statement in the table (Possibly. This is slow.) Or
|
| 340 |
|
|
a table of fast statement number to CSNTE entry mappings indexes into the
|
| 341 |

table. Choice not yet made. */
