Note

You are able to load the address value of a Label with the Command LDL to a register.

This is very useful for example when using Interrupt Service Routines,

because you do not need to calculate the addresses by yourself.

As you only can use LDL, the addresses can not be larger than 255.

If they are larger, only the Low-Byte is used.

So keep in mind that your Labels are placed in the range from 0 to 255.
