Also, the class provides access to custom functions |
1257 | 136 |
These custom functions enable you to call c functions |
137 |
even if no stc compiler is available |
|
138 |
(they are kind of what user-primitives are in ST-80). |
|
139 |
You can register your own custom C-functions in a private main.c |
|
140 |
and relink ST/X from the binaries. |

If you have the stc compiler, we recommend using inline primitive |
144 |
code: its much easier to enter, compile, debug and maintain. |
|
145 |
(especially, to maintain, since the primitive code is contained |
|
146 |
in the classes source/object file - while custom functions are |
|
147 |
external to the classLibraries). |
