How to enter an binary data in Keil?

I've found a topic to do this

#define LongToBin(n) \
(\
((n >> 21) & 0x80) | \
((n >> 18) & 0x40) | \
((n >> 15) & 0x20) | \
((n >> 12) & 0x10) | \
((n >> 9) & 0x08) | \
((n >> 6) & 0x04) | \
((n >> 3) & 0x02) | \
((n ) & 0x01) \
) #define Bin(n) LongToBin(0x##n##l)

By The Way: Note that Keil C51 does provide an extension to the standard 'C' language that allows you to make use of the 8051's bit-addressable features.

You need to look it up in the Manual

This won't help you for writing binary constants, of course.

It works right!
