This class performs compilation into ByteCodes.
|

|
37 |
First, parsing is done using superclass methods,
|
|
|
38 |
then the parse-tree is converted into an array of symbolic codes
|
|
|
39 |
and a relocation table;
|
|
|
40 |
these two are finally combined into a byteArray of the codes.
|
|
|
41 |
|
|
|
42 |
There are many dependancies to the run-time-system (especially the
|
|
|
43 |
interpreter) in here - be careful when playing around ...
