The _emit Pseudoinstruction
The _emit pseudoinstruction is similar to the DB directive of MASM. You use _emit to define a single immediate byte at the current location in the current text segment. However, _emit can define only one byte at a time, and it can only define bytes in the text segment. It uses the same syntax as the INT instruction.
The following fragment places the given bytes into the code:
#define randasm __asm _emit 0x4A __asm _emit 0x43 __asm _emit 0x4B
.

.
__asm {
randasm
}
