Applications of Flags in 8086
- Conditional branching instructions often heavily depend on flags for changing program execution sequence under some situations.
- While doing arithmetic and logical operations, flags help us in recognizing errors that may subsequently institute error handling functions.
- To ascertain that data satisfies specific criteria before going ahead with more processing, details consistency check is performed or limits are checked by flags.
- Direction Flag (DF) and other flags control how data moves when strung together. They give computers a way to work with lists of things efficiently.
- Flags are needed for handling interrupts, since they enable the processor to stop and immediately handle incoming requests depending on their importance.
- Flags are a common feature in loops because they allow for easier completion of iterations.
- They give additional details concerning calculations like overflow / underflow status that then affect other calculations and choices made in decision making.
- Flags help you find out what is happening inside a program.
- Flags not only make decision making easier by aiding logical comparisons since they help determine whether output values are equal or different from each other.
- For debugging purposes, flags, and especially the Trap Flag (TF), can be used to enable single-step execution of instructions. This allows the programmer to follow program flow and to spot potential problems.
