Android Question #define as in C

In C, I would use something like

#define In5 (Inputs1To16[4] == '0')
#define Out5_on Outputs1To16[4] = '1';

and in the C code I could have

if (In5)
Out5_on

The C compiler replaces the code in the source with the definition.
Is something like this possible with B4A or is there something equivalent to #define
