Understanding the Call and Ret Instructions in Assembly Language
Overview of Ret and Retf Instructions In 8086 assembly language, <span>call</span> and <span>ret</span> instructions are crucial for implementing subroutine (procedure) calls. They achieve control flow transfer by modifying the IP or simultaneously modifying both CS and IP, utilizing the stack to save and restore the return address. Principle of the Ret Instruction <span>ret</span> instruction is … Read more

Detailed Explanation of call and ret Instructions in Assembly Language
ret and retf Instructions <span>call</span> and <span>ret</span> are transfer instructions that control the program flow by modifying the IP (Instruction Pointer) or simultaneously modifying both the CS (Code Segment Register) and IP. These instructions are typically used together to implement the design of subroutines (functions). ret Instruction <span>ret</span> (return) instruction pops data from the stack … Read more
