8085 simple subtraction and output
Hey all, I'm new to assembley and this forum, I'm currently doing a module on low level programming in my college course. We were given task to make a simple program and I'm trying to make one that does the following:
Loads '50' into the C register and the accumalator, subtract '1' from the accumalator and output the result, then decrement 1 from the C register until '0', if it isnt 0 then loop back to 'subtract '1'' and continue untill C=0. Then halt.
So far I have:
NXT: MOV A,M
When I try to assemble this I get rc=5 undefined label on line 3 (NXT: MOV A,M)
I'm really stuck, any help would be greatly appreciated, thanks :) (I'm sure that alot of this is wrong but its my first attempt and just need pointing in the right direction please, thanks)
