Hello, I am student working on a school assignment using the Keil IDE and fresh to learning assembly. I am tasked with removing multiple occurrences of a certain word in a character array (more details in the pdf attachment). I have am using the flowchart attached as a guideline and seem to be stuck with the code in the image I have provided. My code seems to be iterating through the loop and increment my counter without exiting.

The load instruction on line 7 is not part of your "Loop", meaning that you are never reading the next character. If you use the register view in the debugger as you step through the code you will see this.
Also, there is no code at your "Equal" label, meaning when you get to here it is likely undefined code (whatever happens to be in memory when you get there). Recommend you put a "b ." branch-to-self instruction as an infinite loop

Actually, you should be able to see that by just stepping through the code with pencil & paper - you don't even need to build or run it!
This is a good practice anyhow - to check that you have written your code correctly.
