Another way is to pad the data with an extra byte, so that there is an even number of entries in the table. This allows the programmer to do a "dummy read" (i.e. reading with post-increment with the sole purpose of incrementing the pointer, with the value read being of zero interest.) This becomes impractical with large data tables, so the <code>EVEN</code> directive can be placed after a series of bytes. If the byte count is odd, <code>EVEN</code> will pad the data with an extra byte. If it's already even, the <code>EVEN</code> command is ignored. This saves you the trouble of having to count a long series of bytes without worrying about wasting space.

 

EVEN ;some assemblers require this to be on its own line</lang>
