Primitives are currently not supported by the compiler
|
|
|
54 |
- if you want a primitive, you must use the stc-compiler and
|
|
|
55 |
link a new smalltalk.
|
|
|
56 |
|
|
|
57 |
In the future, methods with primitives will be passed to stc and
|
|
|
58 |
the resulting binary be loaded into the image (also a limited set
|
|
|
59 |
of numeric primitives could be implemented for more ST-80
|
|
|
60 |
compatibility - if there is a need).
