5. Conditional Jumps

• The most common way to transfer control in assembly language is to use a conditional jump. This is a two-step process:

  • First, test the condition.

  • Then, jump if the condition is true.

  • Continue, if condition is false.

• All conditional jumps except two (JCXZ and JECXZ) use the processor flags for their criteria.

• There are about 30 conditional-jump instructions.

• Each conditional-jump instruction takes a single operand containing the target address.
