Inserts a byte of data into the program with value defined by the input.

Syntax

   .db n		;n is any 1-byte integer
   .byte n

Uses

The easiest way to put data directly into your program. Note that since the z80 processor is little-endian, loading into a 16-bit register from 2 bytes inserted using .DB will cause the least-significant-byte and most-significant-byte to be swapped.
