It describes the memory layout, Plus/4 specific header files,available drivers, and any pitfalls specific to that platform.</P><P>Please note that Plus/4 specific functions are just mentioned here, they aredescribed in detail in the separate <A HREF="funcref.html">function reference</A>. Even functions marked as "platform dependent" may be available onmore than one platform. Please see the function reference for moreinformation.</P><P>Since the Plus/4 and the Commodore 16/116 are almost identical (the latter aremissing the 6551 ACIA and do only have 16KB of memory), the <A HREF="c16.html">C16 documentation</A> is also worth a look. The differencebetween both cc65 targets is that the Plus/4 runtime uses banking to supportfull 64K RAM, while the C16 does not use banking and supports up to 32K RAM.Because banking is not needed, most C16 programs will be somewhat smaller thanthe same program compiled for the Plus/4. However, programs compiled for theC16 will always run on the Plus/4, while the reverse is not necessarily true.</P><HR><A HREF="plus4-2.html">Next</A>Previous<A HREF="plus4.html#toc1">Contents</A></BODY></HTML>?? 快捷鍵說明
