Change value at specific address in assembly
I'm writing assembly in LC-3. I have a register, R1, that points to a specific address. How do I change the value at that address to 0? Unfortunately, this is due really soon, so prompt help would be greatly appreciated! Thanks!

PS: If you don't know LC-3, here are the 15 instructions: ADD, AND, BR, JMP, JSR, JSRR, LD, LDI, LDR, LEA, NOT, RET, RTI, ST, STI, STR, TRAP
