I have hit a wall. In the following fragment:
int a; void main(void) { a = 1; #if ((defined(TEST_1) && (TEST_1 == 27)) || (defined(TEST_2) && (TEST_2 == 27)) ) a = 2; #endif }
the conditional compilation crashes with diagnostic: > > *** ERROR C308 IN LINE 8 OF PreProc00.c: invalid integer const expression >
This comes from V8.02 of C51.
It doesn't matter whether TEST_1 & TEST_2 are #defined in the source file, defined in the compiler's command line, or not defined at all. I can't find anything wrong with my parentheses.
What am I missing here?

If that's a copy and paste from the original, the first thing that's missing is the backslash '\' that's necessary to continue a preprocessor command across several lines ...
!!!!!!!
You are right, of course. I somehow thought that only applied to macro definitions.
(Thanks.)
