Within programming languages, control structures are one of the most useful features. They allow us to say things such as the following:
The most common control structures you may be familiar with are the if and else statements.
As with C and Python, we can implement a control structure like this in Assembly language.
Also included in control structures are loops. You may have seen these in the format of the for loop and while loop.
The following program demonstrates how we can implement iteration via loops and if else structures in Assembly language via branching.
We will be building upon our previous program where we introduced you to the SUB command, and will also explore some new commands including CMP and BLT.
Create a new file called fourth_assem_prog.s in the assem_programs directory.
To this file we are now going to add the following code...
Change the font size
Change margin width
Change background colour
