WebAug 11, 2024 · In general, assembly language does not offer structured statements. Instead it has three constructs: statement labels — these are used to uniquely identify places in code; a "goto label" — also called an unconditional branch, and, an "if condition then goto label" — also called a conditional branch. WebThe LOOP instruction assumes that the ECX register contains the loop count. When the loop instruction is executed, the ECX register is decremented and the control jumps to the target label, until the ECX register value, i.e., the counter reaches the value zero.
