Code:
adr r0, Activator_Done
ldrh r1, [r0,#2]
ldrh r0, [r0]
@@@@@
Activator_Done:
.ascii "zr", "$$"
Soo, by adding #2 allows you to use:
Code:
.ascii "zr", "$$"
Er in other words, two literals could be defined on one literal rather than doing (two seperate literals):

Code:
Activator:
.ascii "zr"
Done:
.ascii "$$"
