I declare a variable unsigned char bdata Kde in a.c.
[in file a.c] unsigned char bdata Kde;
[in file b.c] #include <stdio.h> ..... extern unsigned char bdata Kde; sbit testbit=Kde^1; void main(void) {......}
Keil's doesn't appear a particularly Elegant Solution... From what I recall, the bit/sbit/bdata junk was what Intel introduced in the PL/M-51 Compiler. At the time the Keil C compiler was introduced, PL/M-51 was the de-facto standard compiler for the 8051. So, we adopted the Intel standard. These legacy language elements are sometimes difficult to kill-off or replace without breaking a lot of existing customer source code. Jon
The Buck Stops ... way over there! ;-)
I totally agree and sympathize. However, adding a feature such as
/* foo.c */ bit someBitVar = otherByteVar ^ 1; /* foo.h */ extern bit someBitVar;
