Assembler OR operation

Question

Is this asm code:

or      unknown_byte_0004AAA7, 1

dseg05:000C7FDC unknown_byte_0004AAA7 db 0

equivalent to this C++ code below?

bool unknown_byte_0004AAA7 = 0;
unknown_byte_0004AAA7 = unknown_byte_0004AAA7 | 1;

Thanks in advance.

Answer 1

Almost, but not exactly. bool is not required to be 1 byte long in C++, so I'd declare unknown_byte_0004AAA7 as uint8_t, to make sure it is one byte long.
