Hi Andy,

what do you want ?
Want you stick on pure ANSI 'C' ???
Or want you use the 8051 with some different memory areas and need a mechanism to address any of these ?

By the way, XDATA, PDATA are macros only. So it's easy portable to other memory architectures. Simple exchange the macro definitions in the header file. I think macros are also full ANSI like, isn't it ?


Following my header definitions to make a syntax check on 8051 sources with Borland C, it works nice:

#ifdef __TURBOC__
#define bit char
#define xdata
#define idata
#define bdata
#define pdata
#define data
#define code
#define sfr char
#define sbit char
#define sfr16 int
#define interrupt /##/ // comment
#define _at_ ;/##/
#endif
