Jump Equal (JE)

In ASM2 assembly language, the Jump Equal (JE) instruction is a control flow operation that redirects the program execution to a specified label or function if the zero flag (ZF) is set, indicating that the result of the prior comparison or arithmetic operation was equal (i.e., the comparison yielded zero difference).

Syntax for Using JE: JE <label/function_name> JE EQUAL_CASE

Where:

  • <label/function_name> represents the label or function to which the program control should jump if the condition is met.

Technical Details:

  • Flag Utilization: JE checks the state of the zero flag (ZF) in the status register. If ZF is set (1), indicating equality, program control jumps to the specified label or function.

  • Use in Conditional Branching: Commonly used after a CMP (compare) instruction, JE directs the program flow based on comparison results, facilitating decision-making logic.
