Hello,

Supposing I have a #def like so ..

#define A 10

Now A has been used everywhere in the code.

In loops ... for (i=0; i < A; i++)

And defines ...

int charArray[A];

And in structures

struct a {
   int intarray[a];
};

Now, I want to define a variable B such that ..

#define B ( (my_mode) ? 20 : A)

Basically, B will be A (10 if my_mode is 0 (old) or 20 if my_mode is 1
(new).

Obviously this creates a problem with the integer array and the
structure definitions - I think I can do this only if it is a function
or in the for loop as above.

Is there any way I can achieve this or will I have to hardcode
#define B 20 and live with

int charArray [20]; etc. in all modes .

TIA
