Assembly

Hello, I had a question about incrementing a pointer to the next element in an array!  For my project I am programming in Assembly, specifically in LC-3.  Anyway.

Would something like this

GETC
STR R0, R4
ADD R4, #1
(loop)

Take the value with GETC, store it in the array element R4 is pointing at, and advance the pointer to the next element? I am afraid It might just add 1 to the value AT r4, rather than incrementing the pointer 1, which is its intended purpose.  Any help?

Because language semantics matter, and because when Thompson was coding the MULTICS matters.
